Notes
• REV23M is an electric weekly programmable room
temperature controller.
• The controller conforms to "Software Class A" and is for
use in "normal" pollution situations.
• If the reference room is equipped with thermostatic
radiator valves, they must be set to their fully open
position.
• Remote operation contact T1 / T2 must be wired
separately using a separate shielded cable.
• Ensure that the local regulations for electrical
installations are complied with.
• REV23M can only be used in connection with an
OpenTherm Plus-compatible boiler.
