This reptile thermostat is an older model of the timer thermostat. It allows for two-stage temperature control, day and night. There are two outlets for the heat lamp, but only one can be used. (Because a broken part of the outlet cap remains in one of the sockets) 【Request】 Please refrain from negotiating prices.
