Simplicity is at the heart of Wiser. From a clean and contemporary design, to ease of installation and ease of use, the Wiser Room Thermostat encompasses everything a smart device should. The Wiser Room Thermostat is the key starting point for your system. Allowing you to set time and temperature schedules for each day of the week, you can benefit from cost-saving comfort. The Wiser Heat app enables you to control your heating and hot water from anywhere in the world via your smartphone. As Wiser utilises wireless heating controls, all functions are only a swipe away wherever you are, making staying in control of your home heating simple. Personalise your home heating by adding Radiator Thermostats to your Wiser system. Taking Wiser to a whole new level of smart, they provide the ability to set different schedules and temperatures in different rooms. Ultimate comfort, convenience and energy savings. Inspired by the iconic design of the Drayton TRV4, the Wiser Radiator Thermostat maintains the simplistic style and builds on years of success as a leading TRV manufacturer with a host of additional features that allow room-to-room heating control. If you have existing TRVs, your upgrade to Wiser Radiator Thermostats couldn?t be easier. Simply mount on to existing radiator valves with the ring nut provided. The thermostat is battery operated so there are no wires or fuss. There are adaptors provided with the thermostats to allow fitting on all radiators. In total you can add up to 32 different radiators per system and you can add or remove thermostats whenever you would like. The standard connectivity range from the Hub to the smart radiator thermostats is around 25-40 feet. This is dependent on the position of your Hub, thickness of your walls and distance of your radiators from the hub. If you have a large house or a house with thick walls it may be necessary to purchase a Wiser Smart plug with range extender to make your system more robust.
