Description
The Bard HVAC CMH-14A Outdoor Thermostat senses ambient temperature and signals the system to enable or restrict operation based on preset conditions, supporting controlled performance in varying conditions. It operates through a temperature-sensitive element that responds to external conditions and communicates with the control circuit to manage system activity. Within HVAC systems such as heat pumps and packaged units, it assists in regulating operation according to outdoor temperature changes. Located externally on the unit, it supports proper system response, maintains operational balance, and ensures consistent performance during fluctuating weather conditions.
