Technical Description of IR 10 Heating Controller

Ver. IR10 CTC 400

IR 10 Heating Controller (ver. IR10 CTC 400) is a controller of heating systems with a CTC

heat pump and solar thermal system. The controller can handle 2 heating zones with a mixing

valve, DHW heating by a heat pump, DHW heating by an el. heating element and it can control

a backup source (electric or gas-fired boiler).

IR 10 Heating Controller is controlled by 6 keys. Information is shown on a 4-line display. The

Controller features 6 inputs for temperatures measured (by Pt 1000 temperature sensors) one

universal input for a switch (r.g. a room thermostat) and one input for Ripple control signal.

Further it features 6 relay outputs (250V 3A) and two 0-10V outputs capable of continuous

control of circulation pumps.

The Controller is fitted with an Ethernet interface a service intervention, firmware upgrades and

eventually elementary visualization of the concerned heating system. The Controller also

features an RS 232 and RS485 communication interfaces. As an option, an OpenTherm

module can be connected to the Controller for communication with a heat source.

This Controller controls CTC Heat Pumps.

1 How to operate IR 10 Controller

The controller is operated using 6 keys , , , , C, OK on its front panel.

The DISP key switches between User and Service display.

Note: The Service display is intended to show info on the Controller itself and therefore it is

not needed during common operation.

The keys , are used to browse in the menu. In order to edit a parameter, press OK and

a cursor appears on the parameter. The values of numeric parameters can be

increased/decreased by pressing / keys. Selection parameters (e.g. ON/OFF) are

chosen by pressing keys , . When finished, pressing OK will move the cursor to the next

parameter in the same display. Parameter editing can be also exited without saving by

pressing the key C.

User menu:

2.1 Zones – user settings

In this Menu, a user can adjust these parameters:

T comfort - setting comfort temperature in zone. This parameter makes sense only

when a room sensor is used.

T setback - setting setback temperature in zone. This parameter makes sense only

when a room sensor is used.

Note: During a day, the controller switches the desired zone temperatures between T day

and T night by the preset time schedule..

zone on - Switching on Zone on the User level. When zone is switched off on this

level, the circulation pump and valve outlets will be switched off. The

pump and valve outlets can be activated by frost protection, if active.

Summer/winter mode state

- Switching on/off the function for automatic transition between summer

and winter modes. Summer/Winter mode is intended to turn off zone

heating when the outdoor temperature exceeds the preset threshold

summer temperature, and vice versa, to turn on zone heating when the

outdoor temperature stays below the preset threshold winter

temperature.

summer temp (°C) - If the outdoor temperature keeps above this value for the time set in

parameter summer time, the Controller will switch to summer mode.

summer time (h) - see summer temp.

winter temp (°C) - If the outdoor temperature keeps below this value for the time set in

parameter winter time, the Controller will switch to winter mode.

winter time (h) - see winter temp.

2.2 Time programs – user settings

Time programs can be set either for separate days, or in blocks Mo-Fr and Sa-Su.

When the program is being set for separate days, there are 2 transitions from Comfort to

Setback and 2 from Setback to Comfort for each day.

When the program is being set in blocks, there are similarly 2 transitions from Comfort to

Setback and 2 from Setback to Comfort for the blocks Mo-Fr and Sa-Su. Answering YES to

the question Copy program? will rewrite the respective time program blocks.

If program copying is not desired, let the question be with no and leave the menu by pressing

Holiday mode – specific temperatures in zones can be set for the holiday period.

2.3 OTC curve – user settings

The controller works with a linear characteristics between separate points of the curve showing

how heating water temperature depends on the outdoor temperature. The real OTC curve is

entered into the controller using a 4-point polyline (see Fig.) with points E1; I1 to E4; I4 (cf. the

display picture).

OTC points settings

Point I1 represents the highest temperature that can be calculated by the controller, while point

I4 represents the lowest temperature that can be calculated..

2.4 Heat pump control

A heat pump (or entire cascade if used) can be switched off by the user.

1 – HP cascade on / off (applies to all heat pumps).

2 – single HP on / off

Even when just one heat pump is used, HP cascade shall be on.
