Use this setting if you have a standard gas or oil furnace that is less than 90% efficient. When the furnace is properly sized, a cph of 3 is a good setting. But for this particular model, I need some help. When we moved in back in 2011, a Honeywell TH8320UP thermostat was installed through the Westar Wattsaver program. Increase it by toggling between Standard and High efficiency. So you may see less temp spread if you raise the cycles per hour count. The manual states for gas furnaces that 4 is the proper setting. 3) Position the wallplate against the … I have a Honeywell PRO 6000 which cycles on one degree or less temp change. This controls how many times per hour this t-tat turns on your furnace. When correct setting is selected, press NEXT to display next function. RTH9580WF cycles on/off too often - How to change Cycle per Hour (CPH)? Therefore I have no knowledge of the performance of the furnace prior to this. If your thermostat is placed close to a heat source such as direct sunlight or a heat register, it will skew the temperature reading causing the thermostat to turn on and off irregularly. To change minimum ON time Heating Gas Boilers (30kW) 6 1 No action required Oil Boiler 3 4 a. Controls length of cycles, the lower the setting, the longer the cycles, both on and off. Set to 60°F it will fast cycle 15 minutes on at 60°F, and 10 minutes off at 59°F. Cycles per hour is related to the TPI control feature, along with Minimum ON Time and Proportional Bandwidth. FUEL SWITCH M19497 ON 1 2 3 M19567 BACK OF THERMOSTAT DIP SWITCH Their answer: build a custom thermostat that has an "anticipator circuit", with hysteresis like the old Mercury thermostat. A slightly higher setting to obtain longer burner-on times (fewer cycles per hour) may be desirable for some systems. I guess this is not a new question for Honeywell thermostat, I read a lot of other customers on other HVAC forums with Honeywell have similar complains. RCT8100 Programmable Thermostat Operating Manual 69-2337EF-01 69-2337EF-01.book Page -1 Friday, May 25, 2012 2:24 PM So I called Honeywell. To learn how to adjust your Cycle Rate, check out our Cycle Rate article. 2. Set cycle per hour to 3. Honeywell thermostats are top notch in my opinion. 2) Separate the thermostat from the wallplate as per Figure 1. You can read about this is the Honeywell FAQ: TPI Having the cycles set to 6 per hour, i.e 10 minute periods, does not mean that the boiler will automatically light up every 10 minutes. Their stats use an advanced algorithm to cycle equipment, and cycles per hour is … Cooling cycles per hour 3 2 to 6 cycles per hour 5. This setting changes the number of times per hour the thermostat cycles the furnace on and off. The furnace is a single stage 90% natural gas. Judging by the cycle rates, I think the stat is set for 6 cycles per hour. Heating cycles per hour Note: Make sure system switch is in the heat position. RTH9580WF cycles on/off too often - How to change Cycle per Hour (CPH)? 3. A digital thermostat can be preset to automatically make the adjustments when the temperature deviates from the preset choice, which can help save energy.Digital technology is newer technology; however, even with new technology, there is a need to make sure the thermostat is calibrated to the correct temperature. Note that the screw is captive and cannot be removed from the wallplate. Cycle rate limits the maximum number of times the system can cycle in a 1 hour period measured at a 50% load. Here we describe various types of internal or hidden switches found in some wall thermostats … 0 12-hour display 1 24-hour display When correct setting is selected, press both s and t to display next function. it will do the math and "Looks" head when the temp is going to change and cycles the t-stat on before the temp change is noticed or felt. Cycles Per Hour DIP Switch 1 DIP Switch 2 Steam, Gravity 1 On On High Efficiency Warm Air (90%+ efficiency), Hot Water, Heat Pump 3OffOn Gas or Oil Warm Air (factory setting) 6 Off Off Electric Warm Air 9 On Off In Floor Radiant Heat Check with manufacturer for recommended cycle rate. Position the wallplate against the wall and mark hole ... 2 to 6 cycles per hour. Press the s or t button to select your heating system and optimize its operation: 5 12 min, Gas or oil furnace. Cycle rate adjustment with electronic thermostats is very simple. Kinda hard to say on here how the CPH works. My preferred thermostat is Honeywell's TH8320. Installed a Honeywell programmable thermostat. Set minimum ON time to 4 minutes. Went to the FAQ's at Honeywell and it states: "cycle rate is the ideal number of times a heating system will run, in an hour, to … We in our third winter in our home. by a bit. 365 Compressor Cycle Rate (Stage 1) 1 - 6 Note: This ISU is only displayed when Cool /Compressor Stage is set to 1 stage. Cycle /Hour Minimum ON 6 3 12 6 12 time 1 1 1 1 What to change ... 6 cycles per hour (cph) Pump exercise disabled 24 0 1 0 0 21-34 6-20 … ... shorter cycle rates allow for smaller swings and tighter temp control. Less efficient. This happens on 8-10 min intervals in cold weather. If you feel that your system is turning on and off too quickly, or causing wide temperature swings by turning on and off too slowly, simply adjust the cycle rate. RTH2300/RTH221 15 69-2448ES—03 WIRING ASSISTANCE TROUBLESHOOTING ... Honeywell shall repair or replace it (at Honeywell’s option). It's driving me crazy since the furnace for the second floor is in the attic, and it's loud. In my old place, the stat was of the non programable kind, probably set for 3 cycles per hour. Honeywell does not use fixed differentials. It's cycles per hour at 50% load. Compressor protection 2 1 0: Off 1: On The standard for electric heat is nine cycles per hour.The longer it takes the system to emit all its heat, the longer a cycle should be. Looking for recommendation (Brand and Model) on a programmable thermostat (under $75) where the differential is adjustable. 0: 12-hour display 1: 24-hour display 2 to 6 cycles per hour • 2: 30 min (steam, gravity) 3 Heating cycles per hour 5 • 3: 20 min (hot water, 90%+ high-efficiency furnace) • 4: 15 min (gas or oil) • 5: 12 min (gas or oil) • 6: 10 min (electric) 4. I have an older gas furnace with a new digital non-programmable Honeywell Thermostat. A slower cycle rate provides a bit wider of a temperature swing and longer on/off cycles. You do not need to select a cycle rate as part of setting up your Lyric; it will automatically suggest a cycle rate appropriate for … But in general they maintain the indoor temp very close to the setting and will cycle more than a old mercury stat or low quality nest. Of course the longer the cycles, the fewer there are in an hour. I suspect that when you change the number of cycles, you are not directly setting a specific number of cycles, but changing the difference between the "on" temperature and the "off" temperature.
