Thermostats with Contact Sensor used in HERZ - Pump group Simple
General information
Contact thermostat dimensions
Thermostat data
Type: 1
9420
88
Setting range: 20–50 °C
Max. differential pressure: 0.75 bar for low-noise operation should not exceed 0.2 bar
Capillary tube length: 2000 mm
Hysteresis: 0,3 K
Heating medium temperature influence: 0,15 K / 10 K
Over-temperature protection: 10 K over full scale value
Field of application:
HERZ-Thermostat with floor thermostat, consisting of thermostat with liquid sensor (hydrosensor), capillary tube and
tube probe (M30 x 1.5). It can be mounted on all HERZ valves, which are designed for thermostatic operation.
Installation instructions:
1. Unscrew the screw cap or hand drive from the thermostatic valve lower part.
2. Fully open the thermostatic head, place the union nut on the valve. Turn the thermostatic head so that the handwheel
scale is easy to read.
3. Tighten the union nut moderately with the SW 30 wrench.
4. Check operation by turning the handwheel and adjust the thermostat to the desired temperature.
Contact sensor
The contact sensor is attached to the pipeline by means of clamps, but can also be plugged into a diving sleeve.
Proper heat transfer must be ensured.
Setting of the thermostats with Contact Sensor
The desired temperature limitation can be achieved by following temperature values. Some deviations of temperature
(K) can occur depending on the type of installation and the system design.
