White-Rodgers 1F98EZ-1621 Wireless Programmable Thermostat System

This innovative system takes advantage of the latest wireless technology and allows for the location of a thermostat where wires are difficult or impossible to run.  The system consists of:

1).  6" Comfort Interface (Thermostat) which runs on batteries
2).  Equipment Control Module, which is powered by 24V system transformer and wires to HVAC equipment
3).  Return Air Sensor (RAS) - The RAS monitors temperature of the return air and is needed at all times for system operation

Features:

  • Universal - compatible with single and multi-stage, heat pump and heat pump with dual fuel applications
  • Premium Humidity Control
  • Easy-to-Read 6" Display on Comfort Interface
  • Ideal where pulling wires is difficult and additional temperature sensing is desired.
  • Color-coded LEDs on Equipment Control validates system wiring.
  • Comfort Interface and Equipment Control are paired at the factory - nothing to configure.
  • Wireless Sensor (F145RF-1600) is configurable for indoor or outdoor use. The thermostat displays the average of the local sensor and any indoor remote
    sensors unless a device has been deactivated.  The local sensor can be disabled so that only remote sensor values are used for control.
