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 fi gure below, 

removing the link

4.  If a remote time clock is to be fi tted, (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: 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.
