Your present setup relied on the way double pole 240v thermostats paintings -- one leg is an on/off (disconnect) function, whilst the other leg is thermostatically controlled. This is first-class for walking electric resistance warmers, and additionally in the case of a mechanical thermostat abusable for what the authentic installer did to govern the fans on/off and pump thermostatically.
New thermostat: the new one is aube th115 and is pictured similarly beneath. Wiring manual suggests the usage of four separate wires to connect it, but one of the connecting options i attempted failed to turn the heater and fan on, even though the thermostat become powered. I wonder what is the correct wiring in my case and especially whether l1 and l2 wires need to be related to the same incoming hot cord.
Current setup: the antique thermostat model is 859m and it's wiring is pictured beneath. There's 2 pairs of cables coming out of the wall, two of them with three wires every (purple, black, white) and another pair with 2 wires every (black and white). All white wires are screwed together, black wires pictured at the top are hot (i am assuming those come from the breaker panel). Thermostat has a real off setting. While it's miles on (on the lowest temp) there may be electricity on one of the black wires coming out of it, which seems to deliver strength to a fan in the room (for the reason that there is additionally electricity on the fan at that point). Whilst thermostat is dialed similarly above room temperature there may be also electricity on the alternative black wire popping out of it, and at that point pump is running in the basement supplying warm water to the tubes going through the fan within the room.
