We have wet underfloor heating in our bathroom that's controlled by Honeywell Evohome, with a thermostat in the bathroom, all of which works well. I want to be able to turn the towel rail radiator on in the morning for a period, regardless of the temperature in the bathroom, so that it dries our towels. Is there a TRV that you'd recommend that has a programmable timer function, that won't be turned off by a temperature sensor? Thanks.
