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.
