I've replaced my 20yo Rehau system with this Heatmiser UH8 RF system - had to be wireless because my Rehau room stats are LV 2 core wired, I can't replace the wires in 14 rooms. I've DIY installed 2 of these, upstairs and downstairs, a great piece of kit. Quite straightforward tbh. Fix on wall, connect mains, connect actuators - it has a marvellous "test dip switch" feature that allows you to test everything - Pump, Heat Call, Each Actuator Zone. Once actuators look ok, fit them on manifold, of course make a note of zone/manifold zone. Then, using the NeoAir thermostats, pair each stat against the chosen zone. Easy. Then, install the NeoHub to your router/LAN - this enables online control via the NeoApp. Download and install the NeoApp. Then, pair each NeoAIr stat to the NeoHub using the NeoApp.This allows you to control each stat via the app. I discovered 3 stats furthest away from my NeoHub kept dropping 'Offline'. This was due to distance/walls to the NeoHub. The stats still controlled the UH8 zones, BUT couldn't connect to the NeoHub. Solution - Neo Boost V2 repeater... Pair the Boost V2 to the NeoHub physically near the NeoHub pressing a button. Then, pair to the NeoApp by adding the repeater to the NeoApp. Then, reset each affected NeoAir and re-pair to the NeoHub using the app Then, locate the Boost opposite end of property and the nearby stats will connect and work fine.
