Overview

This OEM PTAC thermostat package for the Tempstar TEB12R34DCA combines the standard PTAC thermostat (1058517), the low-temperature protection thermostat (1059022), and the matching control knob (1058437). The PTAC thermostat handles normal cooling and heating calls on the 24V control circuit, while the low-temp thermostat protects the system in cold conditions by limiting operation that could cause coil freeze-up or compressor damage. When either control fails you may see no response to setpoint changes, continuous running, or loss of freeze protection in cold weather.
