What is a Wire Saver Module?

The wire saver is designed to be used with applicable thermostats in which a 24V C wire is required but the homeowner does not have a C wire connected to their current thermostat. Honeywell's wire saver acts like a splitter and replaces the need for a C wire to be run from the HVAC system to the thermostat. This is the best recommendation to supply power your WiFi thermostat without the presence of a C wire. Please contact your local HVAC provider to inquire about the Honeywell Wire Saver Module (THP9045A).
