Installation
Place of installation
Maximum permissible ambient temperature = 50 °C
Flow temperature control:
In the heating flow; immediately downstream from the
pump if pump is installed in the flow
In the heating flow approximately 1.5...2 m down-
stream from the mixing point if pump is installed in the
return
Return temperature control:
1...1.5 m downstream from the mixing point
Minimum limitation of the boiler return temperature and
maximum limitation of the flow temperature:
1...1.5 m downstream from the mixing point
D.h.w. temperature control:
1.5...2 m downstream from the mixing point
Heat exchanger control:
As close as possible to the heat exchanger
Mounting
The immersion temperature controller is designed for use
with threaded nipple:
Procedure:
1. Drain the piping system.
2. Choose one of the following mounting positions:
The controller may not be mounted upside down and the cable may not
enter from the top.
The minimum immersion length must be 60 mm.

The controller should be mounted in a pipe bend with the sensor facing
the flow.
3. Use threaded sleeve:
4. Fit threaded nipple. If required, use sealing material
(hemp, Teflon tape, or similar).
5. Insert controller into the threaded nipple and fix:
