controlled by thermostat or built-in timer, based on the number of zones calling.

• Controls up to three zones and can be expanded with TotalZone Add-A-Zone zone Control Panel for up to 30 zones.

• Uses virtually any Honeywell four-wire, single-stage, multi-stage, or Trol-A-Temp heat pump thermostat.

• Zone-A-Lone central setback feature.

• Purge timer protects equipment between calls for heat or cool with choice of continually on or equipment controlled fan.

• System and zone damper LEDs indicate system and damper status.

• Individual zone fan control.

• Optional Discharge Air Temperature Sensor for capacity control with adjustable high and low limits.

• Thermal circuit breaker protects panel and transformer from damage if miswired.

The TZ-3 TotalZone Zone Control Panel controls single-stage, multi-stage, conventional or heat pump heat/cool equipment. It controls 2 or 3 zones, and is ex
