The Honeywell Frost Thermostat T4360A1009 is a mechanical control designed to help prevent frost damage to boilers, pipework, and building interiors. It features a tamper-resistant cover and provides a simple solution for managing heating systems in low temperature conditions.
This frost thermostat is typically installed in unheated spaces such as garages or boiler rooms, where there is a risk of freezing. It allows tradespeople to set a temperature trigger point between 0°C and 20°C, automatically activating the heating when temperatures drop near freezing.
