Description
First Company E1394 Low-Limit Thermostat — Open 60°F / Close 30°F
The First Company E1394 is a factory-specified low-limit thermostat (freeze stat) engineered to provide reliable freeze protection for fan coil units, air handlers, and related HVAC equipment. Designed to open the circuit at 60°F and close the circuit at 30°F, this temperature-actuated switch helps safeguard coils and system components from freeze damage in cold-weather or low-airflow conditions.
How It Works
The E1394 monitors ambient or discharge air temperature and responds automatically to protect your system. When temperatures drop to the close setpoint of 30°F, the thermostat closes the circuit — signaling the system to take protective action such as shutting down the fan or activating an alarm. As temperatures recover to 60°F, the thermostat opens the circuit, allowing normal operation to resume.
Key Features
- Open setpoint: 60°F — restores normal operation as temperature rises
- Close setpoint: 30°F — activates freeze protection at dangerously low temperatures
- Designed as a direct OEM replacement for First Company fan coil and air handler units
- Compact design for straightforward installation in tight equipment spaces
- Provides reliable, automatic temperature-based circuit switching
- Helps prevent costly coil freeze-up and equipment damage
Typical Applications
- First Company fan coil units
- Air handling units (AHUs)
- Low-limit freeze protection circuits
- HVAC systems in cold-climate or economizer applications
