    • Up to two remote wired temperature sensors may be used with the ZWTSTAT43 thermostat.
    • External wired temperature sensors can be used the following different ways:
      • One external sensor can be used as the only sensor (disabling the internal thermostat sensor)
      • One external sensor can be used to average its temperature with the thermostat internal sensor
      • One external sensor can be used to report outside temperature on the thermostat display
      • Two external sensors can be used to average the two external sensors (disabling the internal thermostat sensor)
  • 24Volts AC required from thermostat wires.
  • Please note that this thermostat requires  a "Common" wire connection.   A "Common" wire is normally provided by the HVAC equipment and is normally labeled with the letter "C".   If your HVAC equipment does not provide a common wire, please call us for other possible solutions.
