Elk M1 thermostat control, without a thermostat

[Dewy13]

This is my first post so I am hopping this is in the right form. I have a fireplace in the master bedroom that's I have my Elk M1 turn on and off though a relay, their is also a keypad with a built in temperature sensor located in the room as well. I would like to have it be on a thermostat but i don't really want to pay for a thermostat. So I was hoping to create some rules on the Elk like "Thermostat1 is in auto heat, and key pad temp is less desired temp, then turn on output 10" My goal is to just use the web interface to set the temperatures for the thermostat. But before I tried this, I wanted to check and see if this is possible, the main problem I can think of is if the elk wont enable the thermostat with out one plugged in? I don't have the ELK-M1XEP yet, so i also haven't been able to test this. Hopefully that all made sense.

Thanks,

Dewy

You will have a hard time convincing the ELK M1 to emulate a "thermostat", but you can get the same functionality easily. You'll need to use the custom settings to set your temperature. From a keypad(menu 7), or the ELKRMS(additional purchase) software you can adjust the temperature. You will need to make a rule to check every few minutes to see if the temp is lower than the custom value, and if it is turn on the output, etc.

Only downside is you will not be able to set this temp from the JAVA/web interface of the M1XEP. To accomplish that you will need to create tasks that set the custom value to pre-defined temperatures, like 65, 70, etc.

Thank you very much for your help.

I have a similar situation: in the event that we have a power failure, the Omnistats will cease to provide temperature input to the ELK. But, we have a natural gas fireplace which I'd like to fire up if the temperature drops too low while the power is out. After some discussion with the fireplace technicians, I have a way to provide the 3VDC to engage the fireplace, and I'm using an M1ZTS for the temperature reading. There is also a temperature relay at the firebox so I can tell whether the fireplace is on/working. The rules should be simple, essentially

every N minutes when power failed and temperature < 50 turn on fireplace power and turn on fireplace ignition and set variable fireplace heat to 1

every N minutes when power failed and temperature > 65 turn off fireplace power and turn off fireplace ignition and set variable fireplace heat to 0

when power restored and fireplace heat == 1 turn of fireplace power and turn off fireplace ignition and set variable fireplace heat to 0

It would be nice if rules could have high-level guards, like "during power failure" that would enable/disable entire rule blocks.

now I havent looked myselfe yet, but cant you just use a virtul output (in the event of power loss set output 208 on), and check the status of output 208 every n mins... if on run your rule....would this be helpful for your enable/disable rule blocks?
