1. More than 6 zones requires another zone control for each addional 6 zones.
2. Use AT_ _ _ _ _ _ for fan coil zone(s); use 29001, THM-0100, or THM-0200 for radiant zones. THM and 29001 models are dual
sensing.
3. For addional zones, an expansion panel is required, HCE-NN-WVC-ZM. Each expansion panel provides an addional fan coil
zone and 5 addional radiant zones. IMPORTANT: If fan coil/A-Coil will be used for heang, a call for forced air heang will
provide a Y2 signal to the EAV unit (120
O
F water). If 120
O
F water to the oor is not acceptable, a dual sensing thermostat is
required to limit oor temp.
4. Zone 1 requires a dual fuel heat pump thermostat (disable compressor during second stage heang). 29001, THM-0100 or
THM-0200 (dual sensing) recommended for radiant zones.For Enertech MPH fan coils. Uses EWC zone panel. Does not require a
master zone. System may switch back and forth between heang and cooling. For more than 3 zones, use part # AZZXM-2 two
zone expansion panel.
5. For Mul-Aqua and non-Enertech fan coils. Uses EWC zone panel. Does not require a master zone. System may switch back and
forth between heang and cooling. For more than 3 zones, use part # AZZXM-2 two zone expansion panel.
6. Requires buer tank.
