QUESTION: I have two 9580 thermostats one in the office, the other in the main hangar bay (two zones).  When heating both zones or only the hangar, I need the furnace to go full blower with normal scheduling through stages 1 and 2.  When servicing only the small office area, I don't want the system to advance from stage 1.  Unfortunately, the office is so small and the modulating schedule of the furnace is still too much airflow for the office (the zone bypass when servicing the office is the main hangar modulating damper that is controlled via SPC (excess dumps into hangar)).  This damper will be wide open during call for hangar heat.  The main damper control logic is managed through a 3PDT  24 Vac relay. So, I need to block out stage 2 from only 1 zone (office).  The zone ramping schedule of the 9580 works well with the 100k modulating furnace control board, and would like to keep that capability. 

ANSWER: Configure the zone 1 thermostat connector STAT TYPE to G2 (conventional gas/electric) or H2 (heat pump) to allow the thermostat to control staging and use the hangar thermostat on zone 1. Wire only the stage 1 circuits (Y1 and W1) on the office thermostat to the zone 2 thermostat connector (Also connect R, C and G wires). Set dipswitch 4 to the LOCKOUT position. This will configure the zone controller to allow 2nd stage only when the hangar thermostat calls for 2nd stage regardless of whether the office thermostat is calling. When the office thermostat is calling and the hangar thermostat is not, SmartZone will not allow 2nd stage to operate.

ANSWER: The SmartZone controller typically controls staging based on the total system conditions which is the most efficient way to operate a multi-zoned multi-staged hvac system. However, the zone1 thermostat connector on SmartZone can be configured to allow the thermostat to control staging (refer to the top of page 10 of the installation manual). When the zone1 thermostat is configured for staging the ability to lockout 2nd stage with only 1 zone calling is disabled. With the thermostat controlling staging your ability to limit staging will be determined by the features of your Honeywell 9580 instead of the SmartZone control.

ANSWER: Updating your zone controller to a SmartZone 2 zone controller will allow you to use any 24VAC thermostat. SmartZone controls are designed to be universally compatible with 24VAC thermostats including WI-FI models used to control your thermostat remotely through the internet on your smart phone or tablet. You should be able to connect any 24VAC thermostat to a SmartZone control without any problems.

ANSWER: ZoningSupply does not carry thermostats, however, SmartZone controllers are compatible with any 24VAC powered 5 or 6 wire thermostat. Popular brands our customers install with SmartZone include Honeywell, ICM, Braeburn, Nest, Ecobee, Aprilaire, Lux, Lyric,  and MANY others. We suggest you avoid using low priced 'power stealing' thermostats as they may cause intermittent issues if your utility power fluctuates. Power stealing thermostats are typically low priced and can be identified by the lack of a C (common) terminal on the thermostat wall mounting plate.
