4.5 Applications overview

The thermostat supports the following applications, which can be configured via

DIP switches at the rear of the unit. The control output for the damper actuator is

either DC 0…10 V (factory setting) or 3-position (see parameter P47), and for the

heating / cooling output ON/OFF, PWM, 3-position or DC 0…10 V.
