Receiver

REA-R.03/1

Consisting of controller (with integrated radio transmitter) and receiver

(switching unit with relay outputs)

• Mains-independent room temperature controller

• Straightforward, self-explanatory menu selection via setting knob

• Self-learning 2-position controller providing PID mode (patented)

• Choice of operating modes:

Automatic with maximum 3 heating or cooling periods, continuous comfort, continu-

ous economy, frost or overheat protection with one 24-hour operating mode including

one heating or cooling period

• In automatic mode, one temperature setpoint can be entered for each heating or

cooling period

• Optional control of cooling equipment

• Advantageous for retrofitting and upgrading projects

(wireless room unit)

Use

For control of the room temperature in:

• Apartments, single-family or holiday houses

• Offices, individual rooms, consulting rooms or commercially used spaces

For control of the following pieces of equipment:

• Solenoid valves of instantaneous water heaters

Set the start of the holiday / weekday), the duration of the holiday period and period (day of departure / the temperature setpoint ( ). This will enable the controller to maintain the adjusted temperature for a period of up to 99 days. Every day at midnight, the counter subtracts one day.

Heating engineer level Access The heating engineer level will be enabled by pressing simultaneously the warmer and colder buttons and by turning the setting knob counter-clockwise and then clockwise. Sensor calibration If the displayed temperature does not agree with the room temperature effectively measured, the temperature sensor can be recalibrated (recalibration to be made on the heating engineer level.) The displayed temperature can be matched to the effective room temperature in increments of 0.

Periodic pump run / Protects the pump against seizing during longer off periods. Periodic pump run is activated for one minute every 24 hours at midnight. This function can be selected on the heating engineer menu. Periodic pump run active: Operating mode Heating / cooling / / periodic pump run inactive: The controller is suited for cooling applications. The function can be selected on the heating engineer menu. The controller comes set for heating operation (refer to section «Factory settings»).

Mounting and installation of receiver REA-R.03/1 The receiver must be wired with the power supply switched off. Mains voltage may be switched on again only after the unit is completely mounted. • When mounting the unit, the base must first be fitted and wired (L/N = AC 230 V mains supply, LX/L1 = consumers).
