Tempstar PTAC Thermostat for TEB15K50SPA — OEM Control with Knob | Ships Today

Overview

This OEM PTAC thermostat kit for the Tempstar TEB15K50SPA includes the thermostat control (part #1058517) and its matching adjustment knob (part #1058437). As the control center of the packaged terminal unit, the thermostat reads room temperature and tells the system when to heat, cool, or idle the fan. PTAC thermostats endure constant cycling in hospitality and multi-family settings; worn contacts and drifting calibration eventually cause nonstop running, short-cycling, or a unit that won't start. A new thermostat and knob restore accurate, reliable temperature control.
