Timeguard have stopped making the TPT88 controller which has sadly stopped working and I have bought a replacement Floureon unit however the wiring appears a little different. Sensor connections are obvious however the other supply and load connections look different. Wiring diagram for TPT88 is here (http://www.timeguard.com/media/317/tpt88.pdf) and wiring diagram for Floureon unit is here (https://www.ebay.co.uk/itm/FLOUREON-E52-Digital-Room-Heating-Thermostat-Weekly-Programmable-Room-Temperatur-/112588349489). Looking at the current TPT88 wiring (1 = L, 2 = N, 3 = COM & 4 = NO) , supply live (red wire) links to 1; supply neutral (blue wire) links to 2; the load cables from the underfloor heating system link to 2 (blue wire) and 4 (black wire); there is then a bridge from 1 to 3. The new Floureon thermostat has four similar connections L and N for the Supply and N and NO for the Load. Can anybody advise how the cables would be connected to the new Floureon thermostat as the wiring diagram makes no reference to a bridge setup and I am unsure where the blue and black Load wires should be connected. Many thanks....
