DeLonghi TRH0715 is a two-switch model with an adjustable thermostat, making it easy to customize the heating to your desired temperature. With its antifreeze function, the appliance can maintain a minimum room temperature of approximately 42°F (5°C), thus preventing freezing while conserving energy. The built-in timer allows you to program the heater to switch itself ON and OFF at the time of your choice, giving you the flexibility to set up to 48 cycles (1 cycle = 1 “ON” + 1 “OFF”) over a period of 24 hours (12 hours a.m.+12 hours p.m.).
