Honeywell thermostats are top notch in my opinion. 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. 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. The thermostat's job is to maintain the temperature as best as possible, and Honeywell's thermostats are designed to do this. Looking for recommendation (Brand and Model) on a programmable thermostat (under $75) where the differential is adjustable. ... shorter cycle rates allow for smaller swings and tighter temp control. It's cycles per hour at 50% load. RCT8100 Programmable Thermostat Operating Manual 69-2337EF-01 69-2337EF-01.book Page -1 Friday, May 25, 2012 2:24 PM 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 … I have the same problem. Cycles per hour is related to the TPI control feature, along with Minimum ON Time and Proportional Bandwidth. For forced air, you don’t change anything because the thermostat comes set for five or six cycles per hour. Set to 60°F it will fast cycle 15 minutes on at 60°F, and 10 minutes off at 59°F. Of course the longer the cycles, the fewer there are in an hour. Controls length of cycles, the lower the setting, the longer the cycles, both on and off. The problem is that I would like to adjust the furnace so that it turns-on less frequently than it currently does. My preferred thermostat is Honeywell's TH8320. 365 Compressor Cycle Rate (Stage 1) 1 - 6 Note: This ISU is only displayed when Cool /Compressor Stage is set to 1 stage. And again in their CT87A,B,J Round Thermostat instructions Honeywell also states that moving the heat anticipator up will give the burner a longer on time. So I called Honeywell. Increase it by toggling between Standard and High efficiency. 3. So you may see less temp spread if you raise the cycles per hour count. Hello. Set minimum ON time to 4 minutes. To change minimum ON time Heating Gas Boilers (30kW) 6 1 No action required Oil Boiler 3 4 a.

Kinda hard to say on here how the CPH works. b. I have an older gas furnace with a new digital non-programmable Honeywell Thermostat. RTH9580WF cycles on/off too often - How to change Cycle per Hour (CPH)? Less efficient. Quick Installation Guide 4 1) Loosen the locking screw at the bottom of the thermostat. The furnace is a single stage 90% natural gas. 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. Set this to 2 or 3. Note that the screw is captive and cannot be removed from the wallplate. Page 16: Heating Cycles Per Hour When the furnace is properly sized, a cph of 3 is a good setting. This controls how many times per hour this t-tat turns on your furnace. 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. A slower cycle rate provides a bit wider of a temperature swing and longer on/off cycles. Of course the longer the cycles, the fewer there are in an hour.For forced air, you don't change anything because the thermostat comes set for five or six cycles per hour. Installed a Honeywell programmable thermostat. To learn how to adjust your Cycle Rate, check out our Cycle Rate article. When correct setting is selected, press NEXT to display next function. 2 30 min, Steam or gravity system. FUEL SWITCH M19497 ON 1 2 3 M19567 BACK OF THERMOSTAT DIP SWITCH Set cycle per hour to 3. But for this particular model, I need some help. Here we describe various types of internal or hidden switches found in some wall thermostats … On an avg, (about 50% load) the system will run about 3 times an hour. Time display : 24 hour or 12 hour AM/PM format Time keeping accuracy : Typically better than 10 minutes per year Program : 7 day with 4 daily time and temperature level changes Time setting resolution : Time of day - 1 minute Program - 10 minute steps Sensing element : 100K (@ 25 oC ) NTC thermistor Temperature In my old place, the stat was of the non programable kind, probably set for 3 cycles per hour. This article describes the purpose and setting of tiny switches found inside of some room thermostats. Honeywell T4 & T4M Programmable Thermostat Honeywell T4R Programmable Thermostat The T4, T4M and T4R thermostats are designed to provide ... To change cycle per hour b. In fact, the room temp does not change when the heater starts up again. Heating cycles per hour Note: Make sure system switch is in the heat position. 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. The thermostat comes default set at 4 (Four 15 minute per hour cycles). Compressor protection 2 1 0: Off 1: On 2) Separate the thermostat from the wallplate as per Figure 1. 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. Cycle rate limits the maximum number of times the system can cycle in a 1 hour period measured at a 50% load. Press the s or t button to select your heating system and optimize its operation: 5 12 min, Gas or oil furnace. Position the wallplate against the wall and mark hole ... 2 to 6 cycles per hour. The manual states for gas furnaces that 4 is the proper setting. Use this setting if you have a standard gas or oil furnace that is less than 90% efficient. The longer it takes the system to emit all its heat, the longer a cycle should be. This is more advanced than previous thermostats. Their stats use an advanced algorithm to cycle equipment, and cycles per hour is … It's driving me crazy since the furnace for the second floor is in the attic, and it's loud. A slightly higher setting to obtain longer burner-on times (fewer cycles per hour) may be desirable for some systems. Cooling cycles per hour 3 2 to 6 cycles per hour 5. This happens on 8-10 min intervals in cold weather. RTH9580WF cycles on/off too often - How to change Cycle per Hour (CPH)? We in our third winter in our home. 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. 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.

Now that winter is fully in swing here in Kansas, I am reminded … 2. 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. Their answer: build a custom thermostat that has an "anticipator circuit", with hysteresis like the old Mercury thermostat. Honeywell has always been a little vague about this setting: just because you set 3 doesn't mean you'll actually get 3 cycles per hour. (Use this setting if you could turn the fan on and off with a fan switch on your old thermostat.) Honeywell does not use fixed differentials. Thermostat forums has information about selecting, installing, wiring and troubleshooting thermostats for all types of air conditioning systems. Separate the thermostat from the wallplate as per Figure 1. Therefore I have no knowledge of the performance of the furnace prior to this. When we moved in back in 2011, a Honeywell TH8320UP thermostat was installed through the Westar Wattsaver program. These little slide or toggle switches may control the heating system on-off cycle rate or burner-on time in a manner similar to the heat anticipator feature found in other room thermostats. Judging by the cycle rates, I think the stat is set for 6 cycles per hour. Higher number results in less of a temperature swing, more comfortable but harder on the furnace. 0 12-hour display 1 24-hour display When correct setting is selected, press both s and t to display next function. What is the best cycle rate, seems to me its better for the furnace to run longer and over shoot the temp. Honeywell uses an advanced algorithm that fixes deadband at 0 °F. by a bit. Problem is that it cycles on and off at least six times an hour, approximately 5 minutes on/ 5 minutes off. You can adjust the amount of times it cycles per hour (CPH). Cycles per hour (cycle rate) is a measure of how many times per hour your heating or cooling system will turn on and off. Ok for that t-stat, it's setting #240 you want to change to 3. 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.
