INTRODUCTION

Please note to assist TR Engineering in improving customer

service, it is important that the registration card is

completed and returned.

The Activair is a single component unit air source heat

pump, designed to provide hot water or low temperature

comfort heating by extracting heat energy from the

surrounding air.

The Activair has been designed and constructed to give

years of trouble free service, and these instructions are

provided to assist you in obtaining the best performance

with the least trouble and cost.

OPERATING INSTRUCTIONS

The appliance is controlled via the remote programmer

included with the unit. This can be situated anywhere in

the property, enabling management of the settings

without having to access the main unit.

Before starting the appliance, ensure that it has been

installed in full accordance with these instructions and that

all necessary safety checks have been carried out.

The diagram below (Fig 1) shows the programmer layout

with the controls uncovered (lift off the protective flap).

SETTING THE CLOCK

Before starting the appliance, the clock should be set to

enable control of the heat pump via the timer.

Note: the appliance operates on a 24 hour clock only.

Ensuring the programmer is on stand-by (LCD screen will

not be illuminated), press the CLOCK button twice. The

first pair of digits in the clock display will begin to flash.

Press the CLOCK adjustment buttons (+/-) until the current

hour is set.

Press the CLOCK button once more, the second pair of

digits in the clock display will begin to flash. Press the

CLOCK ADJUSTMENT buttons (+/-) until the minutes past

the hour are set.

To return to standby mode, repeatedly press the CLOCK

button until the current time is displayed in full.

Fig 1

SETTING THE TIMER

Using the timer, it is possible to set two separate time

periods at which the appliance will operate.

Ensuring the programmer is on standby (LCD screen will

not be illuminated), press the CLOCK button three times.

The first pair of digits on the clock display will flash and the

timer settings display will read ‘ON’. The number

immediately below this will indicate that programme #1 is

currently being modified.

Press the TIMER ADJUSTMENT buttons (+/-) until the time

is set to the hour you wish the appliance to start.

Press the CLOCK button; the second pair of digits in the

clock display will begin to flash. Adjust in the same way to

set the minutes past the hour.

Press the CLOCK button and set the hour you wish the

appliance to cease operation. Press the CLOCK button once

more and set the minutes past the hour.

To return to standby mode, repeatedly press the CLOCK

button until the current time is displayed. To set a second

programme, instead press the CLOCK button once.

The first pair of digits on the clock display will flash and the

timer setting display will read ‘ON’. The number

immediately below this will indicate that programme #2 is

currently being modified.

Use the TIMER ADJUSTMENT buttons (+/-) as described

above to set the second programme. After setting the

minutes past the hour, press the CLOCK button once to

return to standby mode.

To activate the programme(s), press the TIMER ON/OFF

button once. The timer status display will read ‘1’.

The Activair should now cut in and out according to the

times set. The running indicator will display the SUN

symbol whenever the appliance is operating.

Please note that during the time periods at which the

appliance is set to operate, it will not do so constantly.

When the cylinder water temperature has reached the

required level, the heat pump will cease operation until

the water has cooled or has been used. During these

periods, the SUN symbol will flash in the running indicator

display.

Please ensure that all other required parameters, such as

cylinder water temperature (see adjacent column), have

been set before operating the appliance.

To cease operation in this mode, press the TIMER ON/OFF

button once. The timer status display will read ‘0’ and the

appliance will return to non-timed control mode.

NON-TIMED CONTROL

It is possible to operate the appliance without using the

timer control. Ensure that the clock and all other required

parameters have been set before continuing.

Ensure the timer status display reads ‘0’ and press the

ON/OFF button at the top right of the programmer. The

LCD display and power indicator light will illuminate and

the appliance will start. The running indicator will display

the SUN symbol whenever the appliance is operating.

The appliance will now run until the required cylinder

water temperature is reached, at which time the SUN

symbol will flash in the running indicator display.

Please ensure that all other required parameters, such as

cylinder water temperature (see below), have been set

before operating the appliance.

To cease operation in this mode, press the ON/OFF button

once. The LCD screen and power indicator light will fade.

SETTING THE WATER TEMPERATURE

The appliance can be set to heat water between a range of

40°C and 55°C, depending upon your preference. The

water temperature can be adjusted at any time, whether

the heat pump is running or inactive.

To set the cylinder water temperature, press the

TEMPERATURE ADJUSTMENT buttons (+/-). The

temperature display will change accordingly, before

returning to displaying the current cylinder water

temperature.

When the cylinder water temperature has reached the

required level, the appliance will cease to operate until the

water in the cylinder has been used or has cooled.

OPERATING INSTRUCTIONS

(continued)

OPERATING PARAMETER DISPLAY

In certain circumstances, the unit may enter a temporary

lock-out mode in order to maintain efficient operation.

During such times, a code will appear on the programmer

display (Fig. 1). This is entirely normal and the unit will

automatically resume functioning once it has completed its

reset cycle.

In the unlikely event the appliance does not resume

operation, full descriptions of the operating parameters

and their causes can be found on Page 23.

FROST PROTECTION

As the appliance may be fitted externally to the property

being heated, the water in the system may be in danger of

freezing in very cold weather. As such, the Activair has

frost protection which will bring the heat pump on should

the temperature drop too low. However, to provide

protection in the event of a power outage, a suitable

antifreeze should be added to the system.

DEFROST MODE

If the temperature is cold enough for ice to develop on the

coil, this may become clogged and cause the appliance to

cease operation. Should this occur, the unit will

automatically enter defrost mode. This will divert heat

from the heating circuit back to the coil until the ice has

melted. The DEFROST symbol will appear above the

temperature display (see Fig. 1) during such times.

PRESSURE SWITCH

Should the refrigerant pressure within the appliance reach

too high a level, the unit will automatically switch off until

the pressure has been reduced, whereupon the unit will

restart automatically. Please note that the unit may take

several minutes to restart after the pressure switch has

operated.

Refer to the operating parameter descriptions, Page 23,

for further details.

AMBIENT TEMPERATURE CUTOUT

Should the ambient temperature around the appliance

reach too high a level, the unit will automatically switch off

until the temperature has been reduced, whereupon the

unit will restart automatically. Please note that the unit

may take several minutes to restart after the cut-out has

operated.

Refer to the operating parameter descriptions, Page 23,

for further details.

COIL TEMPERATURE CUTOUT

Should the coil temperature reach too high a level, the unit

will automatically switch off until the temperature has

been reduced, whereupon the unit will restart

automatically. Please note that the unit may take several

minutes to restart after the cut-out has operated.

Refer to the operating parameter descriptions, Page 23,

for further details.

COMPRESSOR OUTLET TEMPERATURE CUTOUT

Should the compressor outlet temperature reach too high

a level, the unit will automatically switch off until the

temperature has been reduced, whereupon the unit will

restart automatically. Please note that the unit may take

several minutes to restart after the cut-out has operated.

Refer to the operating parameter descriptions, Page 23,

for further details.

SHUTTING DOWN FOR LONG PERIODS

If power to the heat pump is shut down for a long period

during very cold weather, it is advisable to completely

drain the system. However, too frequent draining of the

system should be avoided, especially in hard water areas,

as this could lead to the build-up of scale in any heating

circuit.

SERVICING

While it is not necessary to carry out an annual service on

the appliance, regular inspections may be required,

depending upon where the unit is sited. Full details can be

found on Page 22.

SIMPLE FAULT-FINDING

If the appliance fails to start for no apparent reason, carry

out the following checks before referring to the operating

parameter and fault-finding guide (Page 23/24), or calling

your service engineer:

1) The unit may be running through a process to clear an

operating parameter condition. In most cases, this will be

cleared automatically, though if it persists, check the

programmer display (Fig. 1) for an operating parameter

number. Refer to the guide on Page 23 for full descriptions

and remedies.

2) Ensure there is a current ‘heat demand’ from the

programmer. Ensure the programmer clock and timer

controls have been set in accordance with the instructions

on Pages 6/7 or that it is switched on (if in non-timed

mode).

3) Check for failure in the electrical supply.

4) Check for a blown fuse. If the fuse has blown and the

replacement also fails, switch off the mains electrical

supply to the appliance and contact your service engineer.

5) Check the circuit breaker (if fitted). If this has tripped

reset and restart the appliance. If the circuit breaker trips

for a second time soon after, switch off the mains electrical

supply to the appliance and contact your service engineer.

Note: if the appliance has been shut down due to a failure

of the power supply, the programmer contains a battery

backup, which will allow the preservation of all settings

and timings.

If the appliance is operating, but the water temperature is

lower than expected:

1) Check that all isolation valves are fully open.

2) Check the water temperature setting is not too low. This

can be increased by following the instructions on Page 7.

3) Check that the vents on the back of the unit and the coil

have not become blocked, impeding the air flow.

4) Check the unit has not entered defrost mode (the

DEFROST symbol will appear above the temperature

display (see Fig. 1). Should this occur, the heat output from

the appliance will be diverted to the coil, until any ice

build-up has been removed.

5) Ensure there is no air trapped in either the Activair or

the heating/hot water system (Page 24).

If sounds are heard from the appliance which sound like

the passage of water, this is merely the normal movement

of the refrigerant within the unit.

If there is power to the appliance and the programmer is

providing a 'heat demand’ to the unit, yet the unit has not

entered running mode (the SUN symbol has not appeared

above the temperature display), it may be that one of the

safety cut-outs (see Page 8) has operated. These will

typically take several minutes to clear before the unit

restarts.

Other Checks

Ensure the default system settings have not been altered.

These are accessed by holding in the SEARCH button for

five seconds when the programmer is switched off. These

are factory-set and should not require adjustment.

Setting 1 –Factory set at 26.

Setting 2 –Factory set at 18.

Setting 3 –Factory set at 14.

These settings should not be altered from the above

without the express permission of TR Engineering Ltd.

If for some reason the settings do not match the figures

given above, alteration is made via the TEMPERATURE

ADJUSTMENT buttons (+/-).If for some reason the settings

do not match the figures given above, alteration is made

via the TEMPERATURE ADJUSTMENT buttons (+/-).

TIPS FOR IMPROVING PERFORMANCE AND EFFICIENCY

1) Unit maintenance has a dramatic impact upon system performance and service life. Ensure regular inspections are

carried out over the lifetime of the appliance. Dirty coils and fans reduce airflow through the system, resulting in

decreased performance. Regular checks should be carried out to ensure the cleanliness of these components. Refer

to Page 24 for details.

2) Programme the appliance to operate at times when the surrounding ambient temperature is at its highest (e.g.

noon). A thermal store may be employed to allow the retention of hot water at this time for later use.

3) If installed externally to the property being heated, the unit should be protected from high winds, as this can lead to

reduced airflow and efficiency, and also cause frost problems; though avoid siting in areas where the airflow is too

restricted, resulting in recirculation of air over the coil.

4) Well-insulate the pipework to and from the appliance to retain as much heat as possible.

5) Where possible, subscribe to economy electricity tariffs (contact your electricity supplier for more information).

6) Lower temperature settings will reduce the amount of energy consumed by the unit.
