Totaline® TL Series 4-Zone Controller (3H/2C Conventional & Heat Pump)

FEATURES

The TL Series EZ4F controller features a state-of-the-art microprocessor for reliable control of four (4) zones from a single forced-air HVAC system. The panel includes a bright, backlit LCD display with full text for system status monitoring and diagnosis. In addition, each thermostat and equipment terminal has its own color-coded LED allowing for easy monitoring of thermostat and equipment calls. The included supply air temperature sensor allows for constant monitoring of supply air temperature in the plenum. The included return air temperature sensor provides a convenient look at the system’s performance.

TL Series exclusive Electronic Limit Control™ (ELC) technology protects the system’s compressor and heat exchanger from potential issues associated with freeze-up and overheating.

Intelligent TL Series Staging handles equipment staging based on time and temperature, allowing the use of single stage thermostats. Exclusive Economy Mode provides comfort and efficiency control. Supports up to 3-Stage Heating and 2-Stage Cooling equipment.
