ICP Thermostat for YH036GC — VariTech Single-Stage 24V Control | Ships Today

Overview

This is a genuine OEM ICP VariTech single-stage thermostat (part number 1064095) for the YH036GC heat pump. The thermostat is the brain of the comfort system — it senses indoor temperature and signals the air handler, condenser, and reversing valve to call for heating or cooling on the standard 24-volt control circuit. When a thermostat fails, the system may short cycle, fail to respond to setpoint changes, lose its display, or stop calling for heat or cool entirely. Replacing it with the correct OEM control restores reliable staging and accurate temperature sensing.
