The RCM61.22 is used for controlling discharge air temperature in smaller ventilating
and air conditioning installations (by heating and cooling).
Application examples:
•
Individual installations, (kitchens, cloak rooms, storage rooms, etc.)
•
Zone control in larger installations
The following units can be controlled:
•
Heating and cooling valve actuator
•
Air damper actuator
•
Step controller or current valve for electric air heater battery
•
Signal converter
The temperature controlled by the RCM61.22 can be shifted:
•
by the outdoor temperature to obtain summer/winter compensation.
•
by a building automation system to obtain set point adjustment (fixed value shift).
RCM61.22
When ordering, specify quantity, product number and description.
