Hello Gunner! Yes, the Flow-Through Bypass Humidifier will work when heating with a heat pump system. The humidifier uses the warm air supply duct for whole-home humidity distribution. Hope this helps! - Jerry

The humidifier measures 15.75 inches in width, 9.47 inches in depth and 15.75 inches in height.
Hello MD! Thank you for reaching out to us. The Flow-Through Bypass Humidifier allows you to reassemble the side plate with the humidifier port, to customize the orientation for your specific install. We recommend selecting a location for the humidifier on the supply (warm air stream) duct. Return duct mounting is acceptable if there are space restrictions on the supply duct. Hope this helps! - Jerry
The actual duct opening required by the Honeywell HE240 is 9.28 inches wide by 9.43 inches high.
Your solenoid is not working properly. It's an excessively common issue with this brand of humidifier. You'll have to return it for a different one and keep trying until you find one that works which is what Honeywell had told me to do.
Hi Gayle! To set your Honeywell Flow-Through Bypass Humidifier for winter operation please do the following: 1) Turn damper blade to "winter" position. 2) Plug the humidifier transformer back into wall outlet and turn water supply to the humidifier back on by turning the handle on the saddle valve to the left (counter clockwise) until there is resistance. 3) Turn the humidistat to its highest setting and set the thermostat to 10 °F (6 °C) above the room temperature. 4) Observe that water is flowing out of the drain hose. NOTE: The furnace blower must be running to activate the humidifier. 5) Reset the thermostat and humidistat to a comfortable setting for automatic operation. (35% relative humidity is recommended.) Choose the humidity control setting using the combination of relative humidity/ outdoor temperature setting scale on your humidity control dial. Match the dial setting to the outdoor temperature to optimize the humidity level while reducing the moisture condensation on your windows. When the outside temperature is -20 F (-29 C) use control setting 15; when the outside temperature is -10 F (-23 C) use control setting 20; when the outside temperature is 0 F (-18 C) use control setting 25; when the outside temperature is +10 F (-12 C) use control setting 30; when the outside temperature is +20 F (-7 C) use control setting 35; when the outside temperature is above 20 F (-7 C) use control setting 40. I hope this was helpful! Thank you.
