To connect a room thermostat, it is necessary to:
1. - Open the control panel as indicated in
2.- Remove the link "A" from the terminal block on the reverse
of the control panel.
3. - Insert the thermostat cable through the cable grommet and
fasten it by means of the cable-clamp provided.
4. - Connect the thermostat wires to the terminal block
(Diagram A).
5.- If a remote time clock is to be fitted, disconnect the integral
time clock from the P.C.B.
6. - Using a volt-free switching time clock, connect the switching
wires from the time clock following points 1-4 above
(Diagram B).
7. - If using an external time clock and room thermostat, these must
be connected in series as points 1-7 above (Diagram C).
Note: Only a low voltage room thermostat capable of volt
free switching must be used. Factory fitted integral
wiring must not be disturbed when wiring external
controls.
Important!!
DO NOT install 240v wires and low voltage switching wires in
the same cable/conduit, this may cause unwanted induced
voltages in the low voltage switching system.
