ELECTRICAL wIRING ANd INSTALLATIoN

A certified electrician must do the installation of the heater in accordance with applicable
local regulations to ensure safety and reliability of electrical connections. Improper elec-
trical connections can cause electric shock or fire. The connection cable must be of rubber
cable type H07RN-F or its equivalent.
NOTE: Using a PVC-insulated wire as connection cable for the Combi Heater is not allowed
because this material easily becomes brittle when subjected to heat.

Innova Control Unit utilizes two sensors
to power up the Combi heater. One is
the Primary Temperature Sensor (TS1)
and the other one is either the Sec-
ondary Temperature Sensor (TS2) or
the Temperature and Humidity Sensor
(T/H). If the heater is placed less than
200 mm from the wall, TS1 needs to
be mounted on the wall above the
heater and must have a distance of
150 mm from the ceiling. However, if
the heater is placed more than 200mm
from the wall, TS1 must be mounted to
the ceiling over the heater, as shown
in the illustration. TS2 or T/H should
be mounted on the wall opposite to
the heater and must have a distance
between 300mm from the ceiling up
to 1300mm from the floor. See further
details from control panel manual.
