Heating only programmable thermostats?

Does anyone make heating only programmable thermostats for hot water systems? (to comply with energy codes)

    The Honeywell 6000 & 8000 lines can be set up as heating only. Presumably the new T series as well, but I haven't installed enough of those yet to recall offhand.

    Tekmar was the only one I could find. They are really expensive and at first I could not get over that since I needed five of them but I bought one and the looks alone made it worthwhile. Who wants five big thermostats? It is very small. Has an isolated switch because RWC needs to go away at some point and it is incredibly accurate and the anticipator is perfect for hot water. It is a bit of a read to program.

    Any of the Honeywell programmables can be set for hot water heat only. No problem. Ditto White-Rodgers. Both usually at your local friendly big box store.

    He asked for heat only and programmable, not a heat / cool - fan stat that could be used. I figured that was fairly obvious. The Tekmars are the only ones I could find when I looked. If there are any others, Id like to know about them.

    Those HW stats 6000 & 8000 are such that you set them up for heating only. Any reference to cooling and fan switch does not show. Even on the non programmable 5000 the fan switch is renamed as back light (on-off) The system switch gives you the choice of heat or off. (no cool)

    Check out HBX Controls. They have a programmable thermostat that includes a floor sensor. http://www.hbxcontrols.com/thm-0200.php

    Honeywell VisionPro and Prestige series are touch screens and will behave as "heat only" thermostats without any fan switches etc.

    Honeywell T pro t-stats can easily be programmed to heat-only programmable. Used 3 T4's today.

    I have good luck with my honeywell. It doesnt need any batteries and has great build quality. I suspect it will last a long time.
