Frequently Asked Questions

Q: Can I use this digital thermostat controller with both heating and cooling devices?

A: Yes! This plug-in thermostat temperature controller supports both heating and cooling control modes. Simply set your desired start and stop temperatures and the unit will automatically manage your connected heater or cooler accordingly.

Q: Is the thermostat compatible with my country's plug type?

A: This thermostat controller is available in EU, US, UK, AU, and FR plug standards. It operates on a universal voltage range of 100–250VAC at 50/60Hz, making it suitable for use in most countries around the world.

Q: Will I lose my settings if the power goes out?

A: No. This digital thermostat features a built-in data memory function that automatically saves all your programmed parameters after a power interruption, so your settings are retained when power is restored.

Q: Can I use the thermostat function and the timer function at the same time?

A: No — the thermostat (temperature control) function and the timing function cannot be used simultaneously. You must select one mode at a time: either temperature-triggered control or one of the four countdown/cycle timer modes (F01–F04).
