Configuring Power Blocks

If you are installing a Phason Rain Sensor to a PBx-10, you can only install three
additional probes. This is because the sensor plugs into the probe 2 terminal.
Actuator deicing
Actuator deicing opens the actuator by 10% when it has not moved for 2 hours. After the actuator
moves the 10%, it moves back to its proper position. By default, actuator icing is not enabled.
Rain detection
By connecting an optional Phason Rain Sensor to a PBx Power Block, you can detect rainfall and
automatically close curtains and actuators when it is raining. By default, rain detection is not enabled.
After you have enabled rain detection, you need to configure the curtain and/or actuator relays you
want to close when it is raining. Follow the instructions for configuring curtain and actuator relays.
To enable additional probes, actuator deicing, and rain detection
1. In the main window, click Configuration, and then Ventilation.
2. Below Your Power Blocks, select the Power Block you want to configure and then click Configure
Power Block.
The Power Block configuration window displays.
3. Below PBx configuration, select the options you want to configure.
 To enable additional te's mperature probes for a PBx-10, select the probes you have
connected. Do not select probes that are not connected to the control.
 To enable actuator deicing, select Deice enabled.
 To enable rain detection (if you have a Phason Rain Sensor installed), select Detector enabled.
4. Follow the instructions for configuring relays or variable stages, or click Close to return to the
