Honeywell thermostat question

in Thermostats and Controls
Line voltage programmable thermostats . Are they compatible for use with Taco 007 circs ? Had a replacement steam boiler with 2 zones off the coil and we could not get the zones to run constantly . The thermostats would turn the circs on for 1 second , then off for 5 repeatedly . While trying to manually increase the temp on the thermostat it would just lose all power for a sec then reset to factory settings . The customer did not have the instructions and the Honeywell website has 0 literature on these almost brand new thermostats .

Thanks in advance .

    Go to this website--http://customer.honeywell.com. THIS IS IMPORTANT--scroll down to the very right bottom corner of the page, and enter RLV430 in the bottom box. Click on the arrow to the right of the box. A list of PDF's will appear on the left side of the page. Click on RLV430 for the literature.

    The instructions talk it the LRV430 being for electric strip heat. I'm guessing here, but it could be that the stat is looking for a resistive load, which a 007 isn't. You could try callingt the hotline 800-468-1502 or perhaps you can leave a question at http://yourhome.honeywell.com.

    Thanks so much Carol

    Here's the scoop - before we started the job , the customer asked if we check the function of the thermostats after the system is up and running . Well , that's a red herring question which usually means there's been problems before . After over 1/2 hour of us trying to troubleshoot the thermostats , he finally came out and told us he's had ALOT of trouble with the 2 of them . He claimed he had to reset em 40 TIMES each to get them to work properly . I'm guessing they never worked ( not the thermostats fault at all ) .

    We left them off the walls and told him to shoot to a home center and get low voltage Honeywell T-stats . That is a very helpful hint about resistive load T-sats , which we've never seen before . Thanks again Carol .
