Activation of heating or cooling coil is indicated by the blinking of the respective symbol in the lower left
corner of the display.
Power Failure
All the parameters and set points are memorized and don’t need to be reentered. Depending on UP05 the unit will
remain switched off, switch on automatically or return to the operation mode it was in before the power failure.
The deluxe version includes a real time clock with a 48h backup battery powered through a super capacitor. The time
does not need to be re-entered after a power failure.
Frost Protection
The controller will enter frost protection mode if the room temperature drops below 5°C (41°F). All heating outputs will
be fully opened. Frost protection mode will be left once the temperature reaches 10°C (50°F). Frost protection display
will remain until a button is pressed. Frost protection can be enabled/disabled using user parameter UP-09
Operation Modes
•
Comfort: The unit is in full operation mode. All the control functions are operating according to their setpoints.
The unit displays occupied mode.
•
Economy: The set point is shifted according to parameters FC-04. The heating parameter is shifted down and
cooling parameter up. The unit displays unoccupied mode. Fan speeds are limited to maximum medium fan
speed. Economy operation may be disabled with UP-06.
•
Energy Hold Off (EHO): The unit is switched off. All outputs are off. The temperature will still be monitored in
order to activate the unit in case of frost. (If frost protection is enabled). Off and current time is displayed.
Activation of operation modes
•
Via operation terminal
•
Clock: (Deluxe version only) Operation modes may automatically be switched according to daytime and
weekday. The clock symbol will be indicated if time programs are activated.
