Overview

Different control output signals are available and are defined during commissioning
(see below).
On/Off
Y1, Y2, Y3

Q1, Q2,
(2 x NO)
DC 0...10 V
Y10
The valve receives the ON command via control output Y1 (Q1 on RDG16..KN) or
Y3 (Q2 on RDG16..KN) when...
1. the acquired room temperature is below the setpoint (for heating mode) or
above the setpoint (for cooling mode),
2. the control outputs have been inactive for more than the "Minimum output off
time" (factory setting 1 minute, adjustable via P48).
The valve receives the OFF command when...
1. the acquired room temperature is above the setpoint (for heating mode) or
below the setpoint (for cooling mode),
2. the valve has been active for more than the "Minimum output on time" (factory
setting 1 minute, adjustable via P49).
The electric heater receives an ON command via the auxiliary heating control
output (Y..., see Mounting Instructions [3][18]) when...
1. the acquired room temperature is below the "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 limit thermostat (to prevent overtemperature) must be provided externally.
On RDG16..KN the electric heater can be controlled via the On/Off control output
(Q2) by setting P47 to 1. For adaptive temperature compensation: see 3.6.4.
Heating: Output Y1 provides the OPEN command, and Y2 the CLOSE command to
the 3-position actuator. Cooling: Same with Y3 and Y4.
The factory setting for the actuator's running time is 150 seconds. It can be
