Mounting and installation

Do not mount on a wall in niches or bookshelves, behind curtains, above or near
heat sources, or exposed to direct solar radiation. Mount about 1.5 m (5 feet)
above the floor.
· The room thermostat must be mounted in a clean, dry indoor place and must not
be exposed to drip or splash water
See Mounting Instructions M3182
· Comply with local regulations to wire, protect and earth the thermostat
Warning!
No internal line protection for supply lines to external consumers (Y1, Y2)
Risk of fire and injury due to short-circuits!
· Adapt the line diameters as per local regulations to the rated value of the
installed overcurrent protection device.
· The power supply line must have a circuit breaker with a rated current of no
more than 10 A. For US installations use Class 2 rated power supplies.
· Inputs X1-M, X2-M or D1-GND of different units (e.g. summer/winter switch) may
be connected in parallel with an external switch. Consider overall maximum
contact sensing current for switch rating
· Disconnect power supply before removing the thermostat from the mounting
