Comments about Manual Dehumidistat Control:

Used on whole house Honeywell DR65 de-humidifier. Easy to install, you have the option to have the control to mount vertically or horizontally. This is a normally open control, that closes on humidity rise.

In duct, on the wall. Looks good and it IS a Honeywell. They do make excellent temperature and humidity controls. PexSupply is hard to beat, [...] price. Competition beware! [...]

  • Manual Dehumidistat Control


    I am interested in the model on the left in the picture above in white. The description on your site looks likes it is for the humidifer not just the control in the picture. What is the difference between H8908A SPST and the model above. What is the cost and do you have them in stock?

      H8908ASPST is a humidistat and H8908DSPST is a dehumidistat. Both are low voltage, SPST, and can be mounted either vertically or horizontally. Both are currently in stock. Pricing information is visible on the product pages.
