I am looking to be able to switch my pellet stove.
Currently, it controlled by a standard 2 wire mechanical thermostat where you slide the slider on top to control the temperature setting..
I wanted to replace it with one that have a wireless remote control thermostat so it can be mounted on a wall opposite side from the wood pellet but still can be controlled by HE.
are you switching line voltage or a relay at 24 VDC?
I did see limited selection of smart line voltage stats.
Even if it's line voltage couldn't you add a 24 volt relay to switch the 120V
It wont work for me since Sinope need to be hardwired directly to the Pellet Stove.
I am looking for a "Receiver" which is hardwired directly to pellet stove and mounted behind it out of view and a wireless thermostats that controls the receiver behind the pellet stove to turn it on or off.
Just like the Amazon link in the first post above but I wanted similar which also included with zwave plus or zigbee or last resort a wifi. I wanted to be able to either control it with handheld thermostat remote control or from HE.
You should be able to use any [zigbee or zwave] thermostat or temp sensor (as virtual thermostat device) combined with a Zooz ZEN16 or 17 relay at the pellet stove. Then it's just some rule logic to control the relay based on the sensor/ thermostat. I think some of the centralite thermostats are battery powered.
Put a Zwave / Zigbee relay switch behind the pellet stove to turn on / off the stove
Put a battery operated Zwave / Zigbee thermostat on opposite side of the room.
Set up a rule in HE to operate the relay switch when thermostat calls for it
But are there thermostat that can trigger rules in HE from dashboard or from the thermostat itself without being connected directly to the pellet stove? I was thinking all thermostat can be called to trigger on or off state then it turn on the device via pair of hard wire
One other way I could do is to put a contact switch hard wire directly to the thermostat and set up HE rule to enable relay switch when the thermostat closes the contact switch. This method may be less hassle to set up .. hrmmmmm
To fire up the pellet stove, a pair of terminals on the back need to be closed.
To shut if off, same pair of terminals need to be open again.
Right now it have a mechanical thermostat with a mercury contact switch inside that close/open the terminals on the back.
It's a simple off and off switch so no voltage need to be fed into the terminal but I wanted a working thermostat mounted on the wall on the opposite side of the room however I am unable to hard wire the thermostat directly to the pellet stove due to odd placement of the stove and it's in finished basement that have concrete walls.
So it make it a challenging to connect a thermostat to the pellet stove on the opposite side of the room unless I tear a path in finished ceiling and wall to run the wires.
I like the idea of wireless thermostat where I can place it about anywhere in the room when the heat reach to the opposite side trigger the thermostat to shut off balancing the heat in the room rather than having the thermostat shutting off the pellet stove prematurely because it on the wall too close to the pellet stove since I can't run a wire to the other side of the room.
wireless therms i believe are wireless in the sense that there are still wires to the equip.. control of the therm are wireless. as mentioned you can go the route of putting a dry switch inline and using a regular zigbee or other temp sensor and rules or apps to control the stove. i am not sure a therm would work anyway as you say there is no voltage..
Not easy to find a cheap radio thermostat with heat function only.
Cool, Mode, and Fan function will go unused and a waste. That what make it challenging...
I know I could use a temperature sensor and a relay switch then use HE rule to operate the pellet stove but the issue is that we have 4 children where 3 don't own a mobile device yet so they would need to be able to turn it on without a dashboard or mobile access. This is where a thermostat mounted on wall comes into play.
Even I am thinking about just tearing up the damn finished ceiling and wall to run a 2 twisted wire but the pellet stove is sitting in enclosed bricked area and there is no way to hide the twisted wire among the brick enclosement.
When the house was built, the previous owner already had a 120V outlet installed inside the brick enclosement because back then the standard wood stove had a electric fan blower built into it.
We brought the house then we took out the wood stove to install a pellet stove in its' place using the same outlet to operate it however pellet stove uses a thermostat to operate while wood stove only had a built in thermostat to enable the blower when it hot. The same outlet can be used to power a receiver or relay switch.
I would use the relay switch - it should work fine. In addition to the temp sensor, you can also add other devices so that a mobile device isn't the only option to turn the stove on/off. A remote temp sensor can provide the room temp input to your 'system.' A push-button or wall mounted switch can provide another input into your rules for manual activation of the stove, or timed manual activation of the stove (on for xx minutes - maybe also tied to the temp sensor/etc).
Any thermostat that works without a C wire "should" work. The c wire is what allows the thermostat to use the power provided by the HVAC unit. Without a c wire, power is usually supplied by batteries.
You're right, that it would be a waste to use a full function smart thermostat for this application. I would use thermostat you've already got but wire it into the ZEN16's inputs. Then write a rule that uses the temp sensor OR the contacts from the thermostat to control the stove.
these work with hubitat via zwave.. require no c wire (only 2 wires) i use this and the older version in a house in mich for in floor heat.. just battery operated.
I’ll mount it next to pellet stove at first to see if I could set it +10 degree more than desire temp hopefully the remaining room will get at least 75 degree before it shut off at 85 near pellet store
If that doesn’t work then I’ll will go ahead make holes in wall and ceiling to put the thermostats on the opposite side of the room.
I believe the centralite pearl is expecting you to connect wires from the HVAC transformer. I don’t think it will function with nothing connected to its wire terminals on the back.
