Smart Infrastructure Touch screen flush-mount standalone room thermostats 2019-10-29
Mounting and installation
Mount the room thermostat on a conduit box. Do not mount on a wall in niches or
between bookshelves, behind curtains, above or near heat sources, or exposed to
direct solar radiation. Mount about 1.5 m above the floor.
Mounting /
Dismounting
• Do not apply excessive force on screws! The deformation of the mounting
frame may lead to improper connections and operation of the unit.
• Mount the room thermostat on a clean, dry indoor place without direct airflow
from a heating / cooling device, and not expose to drips or splashes water.
• In case of limited space in the conduit box, use the mounting spacer ARG70.3
to increase the headroom by 10mm.
• Before removing the front cover, disconnect the power supply.
Wiring
See the User Manual for the installation instructions enclosed with the thermostat.
WARNING
Wire, protect and earth in compliance with local regulations.
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 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 10 A.
● Use only valve actuators rated for AC 230 V.
● Disconnect from supply before removing the unit from its mounting plate.
● Do not connect more than one fan coil unit to the Qs output of the thermostat.
● Do not connect terminal Y1 or Y2 to either L or N.
• Do not use terminal Y1 or Y2 as AC 230 V power supply.
• Use cables with min 230 V insulation for both SELV inputs X1-M / X2-M since
the conduit box carries AC 230 V mains voltage.
• Several switches (e.g. window contact) may be connected in parallel for both
inputs X1-M / X2-M. However, overall maximum contact sensing current for
switch rating must be considered.
