Google Honeywell t4360A this is what a frost stat looks like, you normally only have a frost stat if the boiler is located in a garage, loft,outhouse, etc if the boiler is located inside the house ie the kitchen I doubt you will have frost protection. Is the room thermostat located in the direct draft of the front door? Every time the front door opens it could be dropping the temperature a lot and kicking the thermostat in.
