CAUTION! Do not use the air heater in a very dusty

environment. Dust may accumulate and cause a defect of

the heater. This is also the case for the room thermostat.

CAUTION! Cover the air heater while spreading sawdust

on the oor. This prevents large amounts of dust from

accumulang on the heater.

CAUTION! The air heater can be used in a dusty

environment (e.g. a poultry shed) if they are cleaned and

maintained more frequently.

2.1.2 Temperature

CAUTION! Do not install the heater in places where the

temperature can rise above 35°C. Higher temperatures

cause the internal components to degrade much faster.

• MTS: a modulang digital thermostat.

• MTC: a modulang digital clock thermostat with

opmiser.

• Interface module; a specially designed interface

Following these requirements when placing the thermo-

stat to ensure the heater funcons correctly:

• Ensure that air can circulate around the

thermostat.

• Ensure the sun does not shine directly upon the

thermostat.

• Do not place the thermostat on a cold wall.

• Place the thermostat on an inner wall free from

draught.

• Never place the thermostat within the throw of

the heater.

• Never mount the thermostat near the aerials of

internal communicaon networks. These emit

radiaon that can disturb the thermostat. Keep

several meters distance.

In all cases, the communicaon between the heater

and the thermostat is based on a two wire, low-voltage

connecon. (see the electrical wiring diagram).

Follow these instrucons to prevent malfuncon of the

installaon and damage to the thermostat or air heater:

Use a cable with the following specicaons:

– Signal cable.

– Shielded and twisted.

– Minimum dimensions: 1 x 2 x Ø0,8 mm2.

– Maximum length: 200 m.

CAUTION! Keep the thermostat cable separated from the

mains cables.

CAUTION! Connect the cable’s earth shield only to the

earth terminal inside the air heater. Do not connect the

other end of the cable’s earth shield.

NOTICE A cable with a thickness of less than 0.8 mm will

result in a poor signal.

NOTICE A cable that is not shielded and twisted may

result in a disturbed communicaon in an EMC

1. Connect the two wires of the thermostat to

terminals 4 & 5 of the rst air heater.

2. Connect the rst air heater to the second air

heater.

3. Repeat for each subsequent air heater.

Each air heater needs an unique number to be recog-

with the J14 switch on the control unit of each air heater:

1. Set the S1 & J14 switches on the control unit as

follows (gure 12):

a. Set the S1 switch of the rst air heater to 1.

b. Set the S1 switch of the other air heaters to 0.

c. Set the J14 switch of the rst air heater to 1.

d. Set the J14 switch of the second air heater to

2, etc.

NOTICE If the J14 switch of more than one air heater is

set to the same number, the system will not work.

NOTICE The air heater must be switched o when seng

these terminals. These terminals need a dry contact.

The heater will always run for a minimum of 30 seconds,

even if the heat demand stops. This is to avoid large

amount of starts and stops.

Aer this, the fan will run for 2 - 3 minutes to cool down,

depending on the temperature.

When the cooling me has passed, a new heat request

will be granted.

The air heater can funcon as a de-stracaon fan. This

is called delta-T regulaon and it is done via the room

thermostat, with a temperate measurement sensor that

is located on the air heater.

The system fan is acvated when the temperaturedier-

ence between the sensor on the heater (the delta-T

NTC sensor) and the sensor in the thermostat is bigger

than 8OC (standard factory seng). This procedure en-

sures an even distribuon of temperature throughout the

building, thus acng as a fully automac de-stracaon

fan.

An NTC sensor is located near (or on) the heat exchanger.

This sensor monitors the heat exchanger temperature.

If the heat exchanger becomes too hot, this sensor will

cause the heang process to stop. Depending on the

temperature, the air heater performs the following

acons:

• Step 1: Power reducon (when possible).

• Step 2: Burner stop, followed by an automac

restart when cooled down (thermostat display).

• Step 3: Burner stop, followed by a Lock Out. A

manual reset is required. (thermostat display).

NOTICE A manual reset can be done on the electronic

circuit board or remotely with the special room thermo-

stat.

Prior to packaging, the safety and funconing of each

air heater is checked in detail. It is also set to the right

combuson eciency.

In general, the heater does not need to be adjusted aer

8. Maintenance

CAUTION! The air heater must be inspected and

cleaned once a year by a qualied installer with sucient

knowledge about the device.

CAUTION! Sucient maintenance is crical in

circumstances such as high humidity, dust, high switching

on/o frequency, etc.

Before performing maintenance on an air heater that is

already installed, do the following:

1. Set the thermostat to the lowest seng.

2. Turn o the power supply to the air heater using

the maintenance switch.

CAUTION! Do not use water when cleaning the air heater.

CAUTION! The heater must be electrically isolated during

servicing.

To perform basic maintenance on the air heater, do the

following:

CAUTION! When cleaning parts of the air heater, use

a dry cloth, brush, compressed air or a vacuum cleaner.

Never use a steel brush.

1. Inspect the heang elements.

2. Clean the fan guard on the outside of the heater.

Clean the fan blades if required.

3. Open the access panel.

4. Clean the inside of the air heater. Focus on the

following parts:

– Body

– Fan blades and motor

– Heang elements

– Temperature sensor

5. Check if the wiring, nuts and bolts are properly

secured and ghtened.

Some checks can only be performed when the heater is

running. Do the following:

1. Reconnect the air heater to the power supply.

2. Switch on the air heater.

3. Check if the heater operates without problems. See

Secon 7 if any errors occur.
