SET UP AND TEST

The boiler controls are fully automatic, making the operation very simple.

Only after the system has been flushed through and then filled with water, inhibitor and set to the correct pressure (pressurized

systems), can the electrical supply be connected.

Check 1. When filling the system check for leaks. The warranty will be invalid if water leaks into the boiler. Ensure all joints and connections are water 

tight. Pay particular attention to those above the boiler.

Check 2. Before connecting the mains supply, check the mains power connections are tight. Loose connections can cause a fire.

INITIAL SET UP PROCEDURE: ( AIR PURGE)

1. Ensure the main electrical supply and the programmer controls to the boiler are off and isolated.

2. Remove the pump live and neutral connection from the control terminal block in the boiler, and reconnect the pump live wire into

the control terminal ‘D’ together with the control signal wire. Connect the pump neutral wire into the control terminal ‘N’ together

with the control neutral wire.

3. Unplug the control block from the main PCB, ensure it is safe and not touching anything. The pump is now fed from the control

signal.

4. Check all air is purged from the system, and set the pump to maximum.

5. Switch on the RCD, and only the control (3 amp or 6 amp) MCB.

6. With the programmer and room thermostat on, check the pump is running and water is flowing. Ensure the whole system, valves

etc. are operating correctly. Continue to run the pump for some time to purge any air. Don’t forget to bleed the pump.

7. Switch off the main supply RCD and MCB. Ensure it is all safe before reconnecting the pump connections to the pump terminals as

originally wired. Reconnect the control terminal block onto the PCB. Check all connections are made correctly, check the main

supply terminals in the boiler are tight, close and secure the top front cover of the boiler.

MAIN TEST PROCEDURE

Only after a satisfactory initial test, proceed as follows;

1. Switch on the main boiler M C B. Switch on the programmer “control” (3 amp or 6 amp) M C B Switch on the R C D unit / Isolation

switch. Check the boiler front panel SUPPLY indicator is illuminated (green).

2. Set the programmer for central heating to ON. Set the room thermostat to be ON. The boiler front panel DEMAND indicator will

flash (Amber). This indicator will illuminate as a steady amber after approximately 1 minute. Following the steady amber, the HEAT

indicator will build up gradually.

3. Check the temperature of the FLOW pipework from the boiler. This pipework should start to rise in temperature. The rate of rise will

depend upon the size of the boiler and system.

4. Check the full system operates correctly. If at any time the temperature difference between the boiler return and flow is greater that

20 ° C, then there is a flow restriction problem, and must be rectified immediately. This function is automatic in boiler controls.

5. The pump is operated from the boiler control. It must be connected to the pump terminals on the boiler control panel. The pump

will run whenever the DEMAND indicator is illuminated (amber) either flashing or steady, and it will also continue to run if the boiler

is hot, even after the demand has ceased. It will turn off the pump when the temperature across the boiler falls below 5°C. A bypass

must be incorporated in systems where the heating load can shut down, i.e. when valves or thermostatic radiator valves are fitted.

See note on the bypass on page 7.

6. The FAULT indicator (red) will only illuminate if there is a problem. The HEAT (green bar graph indicator) and the DEMAND (amber) indicators will 

turn off. The boiler will remain in this tripped state until the fault is corrected and the boiler is re-set.
