4.8 Control outputs
Different control output signals are available depending on the thermostat type, the
position of DIP switches 4 and 5, and parameters P46 and P47 (see section 4.7.2).

The valve or compressor receives the OPEN/ON command via control output Y1 or
Y3 (RDG110: Y11, Y21) when
1. the acquired room temperature is below the setpoint (heating mode) or above
the setpoint (cooling mode).
2. the control outputs have been inactive for more than the “Minimum output off-
time” (factory setting 1 minute, adjustable via parameter P48).
OFF command when
1. the acquired room temperature is above the setpoint (heating mode) or below
the setpoint (cooling mode).
2. the valve has been active for more than the “Minimum output on-time” (factory
setting 1 minute, adjustable via parameter P49).
The electric heater receives an ON command via the auxiliary heating control
output (Y…, see Mounting Instructions) when
1. the acquired room temperature is below “setpoint for electric heater”
2. the electric heater has been switched off for at least 1 minute
The OFF command for the electric heater is output when
1. the acquired room temperature is above the setpoint (electric heater)
2. the electric heater has been switched on for at least 1 minute
A safety thermostat (to prevent overtemperatures) must be provided externally.
When an electric heater is connected directly to output Y21, the current causes the
relay contact to heat up. This falsifies the reading of the internal temperature
sensor. The RDG110 (
device index D and higher) compensates the temperature if
the rated current of the electric heating is entered in parameter 46.
Default setting: 1 A for loads
