A: Yes, you can email firstname.lastname@example.org and request wiring instructions. If you have any other inquiries about our Master Flow products please call Technical Services at 800-211-9612.
A: It depends on how you want it function with the thermostat. If you want to turn on the fan with either the humidistat OR the thermostat then wire them in parallel. Wire them in series if you need both humidity and temperature threshold met (logical AND condition).
A: When it gets over the setting
A: It will turn on when the humidity level rises above the setting
A: When set this switch will turn the fan, or whatever device is wired to it, on when the humidity reaches that point. Example: if you install this switch in a crawl space, set it to 60% and wire a crawl space vent fan to it, the fan will turn on at the 60% humidity level and stay on until the humidity level drops below 60% automatically.
A: This will turn on the fan when the humidity reaches the set point and will run until it is approximately 10 % below the set point. If you have any other inquiries about our Master Flow products please call Technical Services at 800-211-9612.
A: Yes you can add the H1 to any of the Master Flow Power attic Fans. You could also replace the thermostat with the HT1 Thermostat/Humidistat Combo Unit. If you have any other inquiries about our Master Flow products please call Technical Services at 800-211-9612.
A: Yes. If you want the fam to work only for humidity and not for temp then set the temp level on the fan to the highest setting.
A: The fan pulls 1.65 amps with a 1/9th horsepower motor. Yes, this humistat will work with this fan. Remember though, a humistat is a moisture control switch, works when the humidity reaches a certain percentage, not temperature. If you are looking to control crawl space moisture levels I'd pair this switch with a couple of foundation vent fans.
A: well mine runs when humidity is high might run for two three days, when dry its off that is what it should do. but i am no expert...
A: The fan will run, as necessary, trying to get the humidity down to what is selected. If the ambient humidity is high it takes longer. Also, if there is a lot of humidity coming up from the ground it will contribute to the ambient humidity, again, requiring the fan to run longer. Once the value, selected, is reached it might take a while for it to build up enough for the fan to restart. I see the same thing with mine. I just let it do its thing.
A: Humidistats are made to work with one fan. Should you have any further questions, please contact Master Flow Technical Support at 1-800-211-9612.
A: My setup has two humidistats. The first is at the "intake" side of the house and does not supply power to the second humidistat if the outside humidity is above a certain percentage since you don't want to pull in more humid air. So the first gate only opens when humidity is at a certain level outside to allow the second one to engage the fans and vent the crawlspace by pulling in less humid air. In your case, it may be running continuously because the outside air being pulled in is also more humid than the setting which will make things run continuously until the outside air humidity drops.
A: One, make sure you have a 6 mil vapor barrier installed over the crawl space soil. Two, set the thermostat on 60%. If your fans are running 24/7 7 days a week you have: 1. Not enough foundation vents to allow the proper air flow through your crawl space. 2. A moisture or water penetration issue that needs further remediation by a licensed professional - your house is set low or the grading around your house is improperly done allowing rainfall to flow to and under your house.
