Clamp-on thermostat AVANSA TH 2A

Product detailed description

Clamp-on thermostat AVANSA TH 2A for circulation pump

• used to switch on or off any contact, most often an electrical contact (pump phase) - thereby switching the circulation on or off
• this allows the pump to be easily controlled, for example the boiler circuit of a solid fuel boiler, or the charging of a storage tank or a DHW cylinder
• the thermostat can be easily clamped onto the pipe and secured on the other side with a strap so that it does not come loose
• the clamp-on thermostat contains a bimetal element, which by bending activates the contact to switch on or off.

• safety clamp-on thermostat with a spring for fixing to the pipe or manifold
• can be connected as a switch-on or switch-off thermostat
• voltage: 230 V
• temperature range: 20 - 90 °C
• temperature differential: 8-3 °C
• protection rating: IP 20
• insulation class: I
• rate of temperature change:  < 10 °C/min
• maximum controlled temperature: 85 °C
• storage temperature: -15 °C to 60 °C
• output: changeover contact

The bimetallic contact thermostat is used for control depending on the temperature of the heating medium in the pipes on which it is mounted. It can be mounted on pipes up to a maximum diameter of 2" using a flexible steel clamp, which ensures contact between the thermostat and the pipe.

Frequently asked questions

• How do I check that this part is compatible with my manifold? Compare the thread/connection type (e.g. Eurocone EK, M30x1.5) and the dimension given in this product's name with the technical data of your specific manifold - brass manifolds from different manufacturers may have different connection dimensions.
• Must the installation be carried out by a professional? Fitting simple parts (brackets, fittings, flow meters) onto an already installed manifold can be handled by a skilled DIYer; we recommend having the connection to a functioning heating circuit and its balancing checked by a heating technician.
• Why is brass a common material choice for manifolds and their accessories? Brass is a long-proven material resistant to corrosion in water/heating systems, easy to machine into precise threads, and able to withstand the typical operating temperatures and pressures of heating water.
