Honeywell TZ-4 Zone Control Panel Four-zone panel designed to provide first call changeover from any zone thermostat. For most HVAC systems including single-stage and up to three stages of heating and two stages of cooling and heat pump. * Four zones at price of three. * Dual-fuel capacity for add-on heat pump applications. * Compatible with multi-stage and heat pump thermostats. * Expandable using TotalZone® Add-A-Zone® Panels. Controls up to 28 zones. * Uses any Honeywell four-wire thermostat to control any equipment including T8611G2051 Heat Pump Thermostats and Honeywell Multistage Thermostats. * Controls additional stages of heating and cooling based on: Time, adjustable from 5 to 30 minutes. * Percent of zones calling. * Multi-stage or heat pump thermostats. * Built-in Emergency Heat switch eliminates need for expensive heat pump thermostat on each zone. Zone-A-Lone® allows zone 1 thermostat to set back all zones during unoccupied periods. * When opposite calls exist, TZ panel services mode calling first and either satisfies call within 20 minutes or drops it and switches over to opposite mode to satisfy that demand. When all calls are satisfied, TZ panel allows fan operation from any zone through Fan switch on each thermostat. * Setting Fan switch to On from any thermostat turns on fan and closes damper to zones with Fan switches set to Auto. * Resettable circuit breaker protects panel. * Visible LED indicators communicate operation. * Adjustable stage control timer. * Adjustable heating and cooling temperature limits for optional C7735A1000 Discharge Air Temperature Sensor. * Adjustable purge timings. Option two transformers for power when many dampers are needed. * Direct replacement for TZ-3. (this posting is the responsibility of the poster) |
