On-Off control
Two devices may be controlled in case the output setting is 0 (CP13). Y1 controls the outdoor damper. Y2 may
enable mechanical heating or cooling or a fan.
3-point output
A 3 point actuator has an open and a close input. Applying power to the open input will drive the valve or damper
open, applying power to the close input will drive the valve or damper to the closed position.
The running time of the actuator may be preset. We recommend to enter the maximum running time under
maximum load in order to make sure that the damper can fully close and fully open in any circumstance.
In order to open the damper Y1 will be activated for the preset amount of time. After the expiration of the running
time Y1 and Y2 will both be OFF. The damper is closed by activating Y2 for the preset amount of time.
If 0 is entered as running time, the binary output will remain constantly active in open or closed position.
Function of mechanical heating or cooling activation
If there is heating or cooling demand. The controller verifies if free heating or cooling is possible based on control
logic mentioned on the last page. If it is not possible, mechanical heating or cooling will be enabled by closing
contact of Y2.
If free heating or cooling is active, the timer specified in CP14 will start to run. The timer counts the number of
minutes. If the set point cannot be reached after defined number for minutes, mechanical heating or cooling is
enabled. (outdoor damper will remain open until free heating / cooling conditions are not met anymore.
Setting delay to 0, will not activate mechanical heating or cooling while free heating or cooling is active
independent of time.
Function of Y2 in fan mode
In fan mode, the fan activates with a delay defined under CP14 after the outdoor damper starts to open. This will
give the damper time enough to fully open before the fan starts blowing.
The fan switches offwhenthe outdoor damper starts to close.

Input X1: Minimum outdoor temperature. If outdoor temperature is
lower than this temperature, the outdoor damper will close,
independent of demand. There is a 5 °C hysteresis before reset.

CP 17
Input X1: Maximum outdoor temperature. If outdoor temperature is
higher than this temperature, the outdoor damper will close,
independent of demand. There is a 5 °C hysteresis before reset.
