Water sensor
The water sensors (TMW) installed on the water pipes are suitable for heat-
ing and domestic hot water control. The water sensors come with immersion
sensor of different lenghts as follows (Ø 4 mm):
Type code
TMW-(50, 100, 210) / NTC10
TMW-(50, 100, 210) / Pt1000
TMW-(50, 100, 210) / Ni1000

Dimensions:
Install the water sensor on the bend of the water-supply pipe so that the
immersion sensor faces opposite the direciton of flow.
The sensor should be positioned at a point where the water is well mixed.
With heating control install the supply water sensor approx. 1 m from the
mixing point and with hot water temperature control install the supply water
sensor less than 0,5 m from the mixing point
1. Screw the sensor on a welded pipe fitting or T-piece using proper sealing
methods. The case can be turned clockwise at the end of the rst pocket
until the cable's bushing seal goes down.
2. Open the screw-off lid and connect the sensor to the controlling device as
a two-wire connection using weak current cable. The polarity of the cable
is irrelevant.
3. Tighten the bushing seal so that it acts as a seal and repels water.
