Honeywell Home HR924UK evohome Wireless Radiator TRV Heads Multi-Zone Kit for UK, White (Pack of 4)

“The Honeywell Home HR924UK evohome Wireless Radiator TRV Heads Multi-Zone Kit offers a smart, programmable radiator controller from a trusted brand. This four pack of radiator controllers use two-way communication with the evohome controller. The evohome Smart WiFi Thermostat is required for these radiator heads to operate and control with temperature zoning. The HR92 radiator controller will fit a wide variety of thermostatic radiator valves (TRV). Adaptors are available for some older less well known valves – if you already have a TRV head in place, it’s as easy as unscrewing the current TRV head and replacing the HR92 base by screwing it in place. Then snapping on the electronic head and locking it (no tools required). If you do not currently have a TRV in place you will need to consult an installer as it is possible that you will have to drain all or part of your heating system in order to replace the valve body. Enjoy accurate, comfortable climate control with this this radiator multi-zone kit. The four wireless heads allow you to create up to one zone per head. The evohome unit allows up to 12 zones, with potentially more than 1 head per zone. Once installed, the timing programs can be individually adapted to a daily routine. Choose up to 6 set points per day at the desired temperature. Each slim, ergonomically designed radiator controller is made with a robust polycarbonate body for durability. They are battery powered with a two-year battery life and a low-battery reminder visible on the radiator controller screen. The flip-up screen can be positioned so that it can be easily viewed or folded away flat. Each unit features a backlit LCD screen to display the zone name, and local set point temperature. The local set point temperature can easily be overridden by turning the dial at the top of the radiator controller. Override temperatures can be set in half degree increments and are effective until the next scheduled change. There is an open window feature that recognises sudden temperature drop and shuts off the local radiator. The zone temperature changes made at either the evohome controller’s screen or via the remote app will change in real time on the screen on the radiator controller. In cases where the radiator head is covered and may not accurately read room temperature, a single-zone thermostat may be used as an accessory (T87RF). Not only are these well-made and feature-packed, they are easy to install, once the compatibility of the radiator valve is established. Valve mounting technical specification: suitable to be mounted on M30 x 1,5 valves (Honeywell, MNG, Heimeier, RBM, Oventrop). Danfoss adapter included, to allow compatibility with RA/RAV/RAVL versions. For those looking to install heating zones, these radiator heads require no additional zone valves, which makes installation a lot quicker and cleaner. To control the radiator control via smartphone app, store Alexa, Google Home, or IFTTT, a central control unit is required to communicate with your router via WiFi (W-LAN). Please note: this model is specifically designed for UK, suitable for vertical mounting. evohome consists of a number of quality components manufactured by the UK’s leading manufacturer of home heating controls, made specifically for Europe. With the evohome Total Connect Comfort (TCC) app, you can control your heating from anywhere with your smartphone or tablet and viewing and changing your temperature.
