15 Creative Mechanical Thermostat Wiring Diagram Collections - Some programmable thermostats (e.G. Honeywell prestige wiring necessities) need a minimal of 5 wires, and perhaps more relying on what capabilities you need to perform (humidifier, and so forth). The additional fifth twine might be for not unusual; offering stepped down strength from a transformer.
If you have smooth get right of entry to to the present thermostat wires, simply remove and follow the identical path with the new set of wires. You may use cable ties, electric tape, or staples (securing wires and cables article). Be sure to take a totally conservative size on how lengthy your new set of wires need to be. You don’t want to start over, if you come up short.

They're speculated to be 2-pole thermostats, that means they switch each hot legs of the 240v. In reality, the inexpensive ones take a shortcut: only one hot leg is switched thermostatically based totally on temperature, and the alternative is switched off handiest whilst the knob is about to off.
The vintage thermostat you have is a 240v thermostat made to without delay switch real electric powered resistance warmers together with cadet sorts. Those types use 240v best and do no longer use a impartial. The reality that neutral is closely used here is a caution signal.
New thermostat: the new one is aube th115 and is pictured in addition beneath.

I wonder what's the best wiring in my case and specifically whether l1 and l2 wires need to be related to the identical incoming hot cord. Be aware: a preceding installer might also have used a exclusive set of colour wires. This can be a non trouble to preserve music of if a whole new set of thermostat wires is pulled. In any other case tag the wires earlier than casting off from the existing thermostat, or be aware of the terminals each wire is connected to.
