E812/RS Two Stage Tamperproof Thermostat

Product Code: E812/RS

The E812/RS is a high quality vandal-resistant 2-stage tamperproof thermostat designed to accurately control fan convectors in schools, public or commercial buildings to within 0.5°C.

The E812/RS has two stages of control. Below a pre-selected temperature the thermostat will control the high-speed fan to bring the room quickly up to temperature. Once the unit has achieved this level it switches to the low-speed fan for normal daytime use, regulating the room temperature up to the pre-selected temperature setpoint.

Once the room temperature eventually reaches the chosen temperature setpoint the fan is turned off. This makes for quieter operation during normal daytime occupancy periods with the added benefit of rapidly bringing the room up to temperature when the heating is initially switched on.

Remote Sensor (/RS)
This thermostat is designed to be operated in conjunction with a remotely located temperature sensor and therefore does not include the integral temperature sensor within the thermostat body. This provides additional flexibility so that the temperature sensor can be optimally located in the room while the thermostat body is mounted where it is necessary to do so, for example beside a heater or in a riser cupboard.

A choice of standard remote sensors are available, but we can also accommodate to your custom enclosures – please contact us to discuss your requirements with one of our design engineers.

* NOTE – A remote sensor MUST be selected from the accessories section in addition to the main thermostat unit.
