How Many Cables To 1 Thermostat?

[Juliapapa]

Please can you advise how many cables can connect into one thermostat?

I have Warm UP 1 x 800 DWS, 1 x 300DWS and 1 x 600DWS with a OCC2-1991-WA Electronic Thermostat.

Also do you recommend using a self leveling concrete layer over the cable and below the tiles. I will be using insulation board over a concrete floor,then heating cables with floor tiles as the top layer.
many thanks

The thermostat u have is discontinued so I would contact Warmup direct for precise information.
They're current thermostats can handle up to 16amps, so those three systems would be OK into one thermostat.
But CONTACT WARMUP for information on your set up please.

Thanks, Warmup said OK to connect all 3 into
a junction box and then from the junction box to the thermostat.

Any recommendations for insulated tile backer board?

I was considering BACKER-PRO backer boards the 10mm ones.
