Mounting
The supply air sensor (GT4) should be placed in the
supply air duct so it is at least 5 x Ø mm from the fan out-
let or batteries.
NOTE!
Installed by licensed installer
• If air heating and/or cooling coil is used, the supply air
temp sensor shall be placed 5 x Ø mm from those in
the direction of air flow.
• Drill a hole with a diameter of 16 mm in the supply
duct. See the illustrations above and to the right.
• Push the rubber grommet into the drilled hole.
• Press the sensor so far that about 10 mm of the cable
is hidden..
Mounting of supply air temperature sensor and accesories
Direction of flow of water batteries
The illustration on the right shows the connection prin-
ciple of countercurrent liquid flow. The principle is that
the hot water enters the battery last in the direction of air
flow, in order to get the maximum effect in the heating of
the air.
Frost protection
Frost protection sensor should be mounted with the hose
clamp around the water outlet pipe of the battery as
close to the battery as possible. Ensure that the sensor
has maximum contact with the pipe. Fluid pipes should
be isolated in their entirety in order to reduce losses.
IMPORTANT! Ensure that the frost protection sensor is
isolated together with the liquid pipe. Improper installa-
tion or inadequate insulation could cause water to freeze
in the coil with great damage.
