Multi-Stage Heat pump thermostat with single Y first-stage terminals. See Heat Pump Thermostats with Single Y Output section and Fig. 3. Multi-stage and heat pump thermostats are not required to control multi-stage and heat pump systems with TotalZone. They are used only when second stage or emergency heat control from the zone thermostat is needed.
Fig. 3. Typical single-stage thermostat wiring. Heat Pump Thermostats Select a heat pump thermostat from Table 1. If the thermostat selected has a separate Y1 and W1, see Fig. 4. When using the thermostat to control the second stage of heat (W2), set DIP switch 5 to On, and DIP switch 1 to Off.

TZ-3 TOTALZONE® ZONE CONTROL PANEL OPERATION Sequence of Operation On a call for heating or cooling, the zone damper stays open to the calling zone, and the dampers close to the zones that are not calling. The TZ-3 panel brings on the heating or cooling and conditioned air is delivered to the calling zone until that zone is satisfied.
When the Em Heat switch or a Cool thermostat puts the panel in the emergency heat mode, the heat pump is locked out and calls for heat are sent to the E terminal. A heat pump thermostat can also control emergency heat from the thermostat system switch.
