Io-hvac-controls UT32-NS Programmable Touchscreen Thermostat

OVERVIEW

The UT32-NS programmable touchscreen thermostat can be used for occupied and unoccupied scheduling of the ZP4-ESP-FAV and the ZP6-ESP zone control panels. When wired and configured properly, the thermostat takes the place of a separate 7-day clock, night stat, and override timer. The UT32-NS Programmable Fan option is used to trigger the ‘G’ fan relay to open or close the Night Stat terminals on the ZP4-ESP-FAV or ZP6-ESP panels that place the systems in the occupied or unoccupied mode of operation. The thermostat can also be used with a -S1 Indoor Remote Sensor. 24-volt power to the thermostat T is supplied by the zoning panels through Night Stat terminals. The thermostat also has a battery backup to maintain the real-time clock in the event of a power failure. The thermostat can be configured to provide 7-day scheduling with 2 or 4 events per day. For commercial schedules, 2 events per day are typical. Refer to wiring diagrams in appropriate zone control manuals.

HOW IT WORKS

The UT32-NS does not control the HVAC equipment and only uses the ‘G’ fan relay to put the zone control panel in either the occupied or unoccupied mode. This is accomplished by using the Programmable Fan option so that the fan relay is energized during occupied mode (Always On) and de-energized during unoccupied mode (Automatic). When in Automatic mode, the fan relay will only energize when the temperature rises above or falls below the programmed unoccupied heating and cooling setpoints

RECOMMENDED SETUP
Refer to the Installation Instructions to configure the thermostat. Leave all other setup menu items not shown below in the factory default

SYSTEM SWITCH SETTINGS
