Room Thermostat / Remote Clock Connection

The boiler connections for external controls are 12V DC and so only controls of 12V DC that have voltage free contacts should be used. The boiler connections for external controls are 12V DC and so only controls of 12V DC that have voltage free contacts should be used.

To connect a room thermostat, it is necessary to:

1.Open the control panel

2.Loosen the cable clamp using a screwdriver and insert the wires leading from the room thermostat

3.Connect the wires to the terminals as indicated in the figure below, removing the link

4.If a remote time clock is to be fitted, (using a volt free switching time clock) connect the switching wires from the time clock following points 1 - 3 above (Disconnect internal time clock)

5.If using an external time clock and room thermostat, these must be connected in series as shown in diagram C, (Disconnect internal time clock)

6.Ensure that they are well connected and not subject to stress when

the control panel is closed

NOTE: WHEN CONNECTING THE BOILER TO EXTERNAL CONTROLS, DO NOT RUN 240V

CABLES FOR SWITCHING CIRCUITS (WHICH ARE LOW VOLTAGE) TOGETHER USE

SEPERATE CABLES TO PREVENT INDUCED VOLTAGE ON THE LOW VOLTAGE CIRCUITS.

Note: y plan system switch 240v and are therefore not suitable system control systems unless a suitable relay is used to switch the low voltage control circuit.

Do not connect 240v to the TA1 switching circuit. Connectiong 240v to the TA1 switching circuit will damage th P.C.B. and invalidate appliance warranty.
