EPH Pipe/Cylinder Thermostat - White

The EPH Pipe/Cylinder Thermostat operates within a temperature range of 0-90°C.

This thermostat is designed specifically for heating applications, such as hot water cylinders and central heating pumps.

SPDT stands for Single Pole Double Throw. It means the thermostat has a common terminal, a normally open terminal, and a normally closed terminal, allowing it to control circuits for both high and low limit functions.

With an IP20 rating, this thermostat is designed for standard indoor heating system environments and is not protected against water ingress, making it unsuitable for direct outdoor exposure.

The temperature setpoint can be adjusted using the external dial located on the thermostat unit.

The switching differential is ±5°C, meaning the thermostat will switch on when the temperature reaches the setpoint minus 5°C and switch off when it reaches the setpoint plus 5°C (or vice-versa depending on the application).

Verify power supply to the thermostat. Check wiring connections and ensure they are secure. Confirm the temperature is within the operational range and that the setpoint is correctly adjusted.

Ensure the thermostat's sensor has good contact with the pipe or cylinder surface. Check for any insulation or obstructions between the sensor and the monitored surface. Recalibrate the setpoint if necessary.

Adjust the setpoint slightly to widen the gap between the on and off temperatures, or consider if the ±5°C switching differential is appropriate for the application. Ensure the system load is not causing rapid temperature fluctuations.

Tamperproof versions are designed to prevent unauthorized adjustments. Use the appropriate tool or method specified for your model to make adjustments.
