Mounting
A mounting bracket is provided for fitting onto a square conduit box with 60 mm fixing centers.
A conduit box of at least 50 mm in depth to accommodate all wire connections is recommended.
After installing the mounting bracket, wire all terminals of the thermostat. Secure the unit to the mounting bracket as described in the mounting instructions (Document ID: A6V15113831 ) enclosed with the thermostat.
WARNING
Carefully read all wiring diagrams prior to installation to avoid damage to the device caused by incorrect wiring of high or low voltages.
Wiring
WARNINGRisk of fire and injury due to short-circuits!
- Adapt the line diameters to the rated value of the installed overcurrent protection device as per local regulations.
- The AC 230 V mains supply line must have an external circuit breaker with a rated current of no more than 10 A.
- The maximum current loading (including fan and valves) is 5 A.
- Use only valve actuators rated for AC 230 V.
- Isolate the cables of all SELV terminals (X1, M, MB+, MB- and Ref) from AC 230 V.
- Disconnect from power supply before removing the unit from its mounting bracket.
- Do not connect more than one fan coil unit to the Q1, Q2 and Q3 outputs of the thermostat.
- Do not connect terminals Y1 and Y2 to either L or N.
- Do not use terminal Y1 or Y2 as AC 230 V power supply.
