1. When the thermostat is powered up, a closing command for the actuator
running time + 150% is provided to ensure that the actuator fully closes and
synchronizes to the control algorithm.
2. When the thermostat calculates the positions "fully close" or "fully open", the
actuator's running time is extended + 150% to ensure the right actuator
position is synchronized to the control algorithm.
3. After the actuator reaches the position calculated by the thermostat, a waiting
time of 30 seconds is applied to stabilize the outputs.
3.7.2 Control outputs configuration (setting via DIP
switches or Modbus commissioning tool)
For the control outputs of a 2-pipe application, either On/Off or 3-position can be
set via DIP switches or via Modbus commissioning tool (see section 3.4). Other
applications, e.g. 4-pipe and 2-pipe with electric heater, only have On/Off type of
outputs.
The application and control output can be changed between On/Off and 3-position
via Modbus.
