ICP Thermostat for 1164300 — OEM Temperature Control 2H01109H | Ships Today

Overview

This is a genuine OEM thermostat (sensing temperature control) for ICP/Tempstar/Heil equipment, replacing factory part number 2H01109H (TSTAT S). It opens or closes a low-voltage circuit in response to temperature, providing limit, fan, or staging control depending on its application within the unit. A failed thermostat can leave the system unable to start, cause a blower or burner to run continuously, or trip a safety limit. The control uses a snap-acting bimetal element with a factory-calibrated setpoint and differential, rated for 24V control circuits.
