Honeywell HZ432 TrueZone Control Panel and Compatible Thermostats

The HZ432 True zone panel has various applications.

• It can control Single-stage, multi-stage conventional, or heat pump heat/cool HVAC equipment up to 3 stages of heat and 2 stages of cool

• Controls 2, 3, or 4 zones and is expandable to 32 zones

• Can control 2, 3, or 4 zones with wireless thermostats when used with the wireless adaptor.

For thermostat control, there are 3 options depending on whether your system is single stage, multistage or heat pump (or all 3):

1. Non-Wi-Fi thermostats

Compatible thermostats for this application include TH1110D2009 – for single stage system, TH6220U2000 - for multistage system, TH4210U2002 – for heat pump system.

Sample connection for a thermostat to a true zone panel. For correct wiring, please see manual.

2. Wi-Fi thermostats

Compatible thermostats include TH6220WF2006 – for multistage system, TH6320WF2003 – for system supporting single, multistage and heat pump.

3. Wireless adapter to HZ432 with Redlink Capability

Redlink is a protocol developed and maintained by Honeywell and uses the 900MHz band (902 - 928MHz)

Thermostats with redlink capability needs to be connected to THM4000R1000 to achieve wireless connectivity to the truezone panel.

The thermostats for the above application include TH5320R1002, TH6320R1004, and TH8320R1003.

For remote access of thermostats with Redlink capability, consider the THM6000R7001 Redlink internet gateway.

See below sample connection set up with the true zone panel for heat pump, 2-heat/1-cool with electric auxiliary heat.
