CCTHV Inputs

Digital​

The two digital inputs must be used with COM2. Terminal COM2 supplies 30Vdc and the digital inputs sense if this voltage is present or not. A contact must be closed between COM2 and one of the inputs to detect a signal. Those inputs are optically isolated.

0-10Vdc​

This input could read as a 0 to 100% and °C value using the corresponding BACnet objects.

The thermostat algorithm can use a remote temperature sensor instead of the internal sensor. See the "Temperature" section.

The input impedance is 30KΩ.

Remote temperature​

Terminals used for a remote temperature sensor of 10KΩ @ 25°C. Here are some compatible temperature curves:

  • Dale curve #1

  • ATP curve Z

  • BAPI curve #2

  • Mamac curve #12

  • Greystone curve #2.

The thermostat algorithm can use the remote temperature sensor instead of the internal sensor. See the "Temperature" section.
