Overview
This is the genuine OEM PTAC thermostat assembly for the Tempstar TEB15R50DCA packaged terminal air conditioner, covering the main thermostat 1058517, the low-temperature thermostat 1059022, and the control knob 1058437. The main thermostat senses room temperature and cycles the compressor, blower, and heat through the 24V control circuit, while the low-temp stat acts as a freeze-protection limit that prevents the coil from icing or the cabinet from operating below safe temperatures. A failed thermostat leaves the occupant unable to set temperature; a failed low-temp stat can allow coil freeze-ups or nuisance lockouts. All three are exact factory replacements that fit the existing control pocket and harness with no rewiring or recalibration.

Compatibility
Engineered specifically for the Tempstar/Heil TEB15R50DCA PTAC. Parts 1058517, 1059022, and 1058437 are the exact thermostat, low-temp stat, and knob the unit shipped with, so they install without adapters, controller changes, or recalibration.
Installation Guide
- Safety First — Disconnect power at the cord or breaker and verify zero voltage with a multimeter before touching wiring.
- Access — Remove the PTAC front grille and control-housing service panel to reach the thermostats.
- Document — Photograph all thermostat and low-temp stat wire terminations and the knob position before disconnecting anything.
- Remove — Pull the old knob, release the mounting clips, slide the thermostat and low-temp stat out, and disconnect the low-voltage leads.
- Install — Seat the new 1058517 thermostat and 1059022 low-temp stat, reconnect leads exactly as photographed, then press the new 1058437 knob onto the shaft.
- Test — Restore power, run a cooling and a heating call, and confirm the unit responds to the dial and holds freeze protection.
