    thermostat with CPH setting

    I've been looking for a thermostat with a cooling cycles per hour setting and it looks like almost none offer this. The only one I've found so far through from searching this forum is the honeywell 6110, but that doesn't seem widely available. are there any other models available? looking for something cheap as the only setting I need is for it to be programmable.

    is there a reason it's so difficult to find thermostats with a CPH setting?

    Any Honeywell digital programmable thermostat will be a CPH thermostat.

    How many times must one fix something before it is fixed?

    I have not found that to be the case unless I'm mistaken on what the cph setting is. I currently have a programmable honeywell Model # RTH2300B and only the heating cph can be set. the manual says cph can not be set, and with poor duct placement, that means frequent ac cycling. I have also looked at dozens of different honeywell thermostats and their manuals and have only found two that have a cph setting, and they appear to have been cancelled/unavailable.

    okay...so not all programmable ones will have a cph setting? what high end non box store models are there? I was under the impression even the vision pro series didn't have a cph setting.

    just to be sure, does that mean if on the vision pro 8000 series I have the CPH to 4, when the demand for cooling turns on, it will stay on for at least 15 mins? and after it turns off, it will stay off for at least 15 mins?

    1 cycle is the combined on and off time. So 4 CPH would be on 7.5 minutes, off 7.5 minutes, 4 times in an hour.

    On Honeywell thermostats, temp always over rides CPH. So it will not always do the set CPH.

    Another member here has a TH8110 for sell. You can contact him through his email address. Its in his profile under "About me".

    if temp over rides the cph, what's the point of it? does adjusting it even do anything?

    The VisionPro thermostat is sturdy, proven, and offers cooling cycles per hour adjustment. Go for it.

    • Refrigeration makes the HVAC psychrometric process happen.
    • HVAC pyschrometrics is what makes indoor human comfort happen...IF the ducts AND the building envelope cooperate.

    It attempts to mimic a heat anticipator, and prevent large temp swings.
