U05 Thermostat (TP32U05YRK)

A powerful and versatile choice, this thermostat works perfectly with most York systems — single or dual capacity units with ECM or PSC blower motors. Comfort Talk, text based output, dual fuel capability, and 4-wire installation are only a few of the features that make this thermostat a great partner for your geothermal system. 4-wire compatibility allows easy upgrade from old single stage heating and cooling equipment without having to update to 8 wires.
