The thermowell is fitted with a 1/2" external thread, which is to be screwed into the coupling collar
fitted at the spot where you need to measure temperature (piping, tank). The thermostat's sensor is
inserted into the thermowell so that the body of the thermostat is in contact with the thermowell. It
is then secured in this position using the screw on the plastic collar.

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 electric 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.
