Thermostat Description
(see Fig. 1)
1 – activation indicator LED
2 – display
3 – up arrow (increase value)
4 – down arrow (decrease value)
Installation
1. Place the thermostat firmly onto a heater pipe and secure it with the enclosed tension spring so that
the thermostat (temperature sensor) is in direct contact with the pipe. (Any insulation on the insta-
llation spot must be removed before mounting the sensor. To achieve a more accurate temperature
measurement, it is recommended to use a heat conductive paste and clean the contact surface of dirt.)
2. Any excess spring can be cut off.
Electrical Connection
1. Remove the 2 screws on the front housing of the thermostat.
2. Carefully remove the front housing.
3. Connect in accordance with the following diagram (see Fig. 2):
Pump
Power – 230 V
Jump – jumper
PE – protective earth, prevents injury by electrical current
4. The thermostat features a screwless conductor connection. Press downwards onto the top plastic
connector with e.g. a screwdriver. The terminal contact will release. Plug in the conductor. Repeat
the process for all conductors needed for connection. Replace the screws.
The device may only be installed by a professional plumber in accordance with the connection
diagram. In addition, the connection must meet up-to-date, valid VDE standards and specifications
of your energy provider. Installation must always be performed when power is turned off; follow
safety specifications. Maintain the maximum switched load listed in technical specifications! The
manufacturer is not liable for inexpert installation.
Putting the Device into Operation
Connect the thermostat with pump according to instructions.
Connect the thermostat to 230 V power supply.
Short-press the
button.
The currently set mode and heating/cooling mode setting will flash on the display (e.g.: F1/C1).
Then, the current temperature will be displayed.
