The ERC is an advanced Room Controller for Temperature Control in Individuals room, Heated or Cooled by Radiators, Cooling ceilings, VAV or Ventilation and Air Conditioning Systems.

The ERC has two operational modes incorporating an Deadband.

In Heating mode, the unit accurately measures the space temperature and gives a proportional output once the temperature has fallen below a setpoint.                

In Cooling mode, the operation is reversed so that the output is produced when the temperature exceeds the setpoint.

For control of:

  • Valve Actuators

  • Air Damper Actuators

  • VAV Compact Controllers

  • Electric Power Controllers

  • Constant or Variable Air Volume Systems

Suitable for use within the temperature range +5...30C by Numeric Scale or Mid Position 21C setpoint adjustment by Swelling Arrow.

Blend with any interior environment.
