I really wasn't sure how to title this msg. i have a building w/ 3 apts heated by a single boiler. currently there is one unit which maintains the thermostat.
i would like to monitor the temp in each unit, but control the boiler from the utility room. oh yeah, and i don't want to pay for some fancy overpriced zoning system.
it would be nice if i could do this w/ some type of wireless sensors--i see wireless thermometers always available for about $20 or so. it seems like there should be some way to modify these to do what i want. i don't know enough to be able to do this on my own, but i'm smart enough to follow instructions if anyone has some ideas.
hard-wired isn't necessarily out of the question, but i have no idea how i might use 3 living area thermostats and set a control temp that may not match any of them.
what i'm trying to avoid is having a single tenant freeze out or sweat out the other two. at the other extreme, i don't want the boiler responding to all three tenants setting their therms to 85 degrees.
i'm hoping that by having temps reported from the 3 living areas to a "master" thermostat i can create some reasonable control. IOW, i need actual temp readings from the remote locations (rather than just on/off signals) so that a thermostat in an unheated basement can control the boiler. i hope that makes sense.
any ideas? TIA.
