Tempstar PTAC Thermostat Kit for TEB09R34SPA — Includes Control Knob | Ships Today

Overview

This OEM thermostat kit for the Tempstar TEB09R34SPA packaged terminal unit includes the PTAC thermostat (part 1058517) and its matching control knob (part 1058437). The thermostat reads room temperature and cycles the unit's heat and cool stages to maintain the setpoint, while the knob is the operator control used to dial that setpoint in. When the thermostat fails, the unit commonly short-cycles, overshoots, or runs without ever shutting off; when the knob is cracked or stripped, accurate adjustment becomes impossible. Replacing both together restores reliable, repeatable temperature control.
