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.
- Easily Reduces Hot and Cold Spots in the Home
- Comfort Interface and up to 3 wireless temperature sensors can be located in optimum control locations.
- Maximizes Comfort with Premium Humidity Control
- Set and control humidification and dehumidification right at the Comfort Interface.
- Optimizes Efficiency on Heat Pump Systems with Dual Fuel Control
- Choice of dual fuel control with wireless temperature sensor or by Dual Fuel Logic program in Comfort Interface.
- Choice of 7 day or Ĝ day/non-programmable (installer selectable)
- Choice of 4 or 2 program periods per dayPermanent program retention during power loss
- Indefinite setpoint Hold or temporary temperature override
