Honeywell HE360 Humidifier Details
The Honeywell HE360 Humidifier is a whole-house unit that mounts on the supply plenum and adds moisture to the warm air from the furnace. Water is spread evenly over a pad. Warm, dry air passes through the pad, picks up the evaporated water and carries it through the home. Because humidified air feels warmer, you can often lower your thermostat heating setpoint and save on fuel. The manual also notes that it helps relieve dry skin, scratchy throats and irritated nasal passages, cuts down on static shocks and protects wood furniture.
Installation starts with a level line drawn on the plenum, since a level unit gives the best performance. The installer tapes the supplied template in place, cuts a rectangular opening and removes the cover and pad assembly. Securing clips and plastic tabs sit on the upper sheet metal edge of the opening, and sheet metal screws hold the housing in place. Do not mount the unit on the furnace body or anywhere that could damage the air conditioner A-coil. Leave enough clearance in front of and above the unit to remove the cover easily.
For plumbing, install a code-compliant shut-off valve. Never tap a line connected to an air conditioner or a gas line. Use plastic (Delrin) compression rings with plastic tubing and copper rings only with copper tubing. Discard the copper ring supplied with the valve when using plastic tubing. Tighten the compression nut only moderately to prevent leaks. Route the drain line on a continuous downward slope to a floor drain. If no floor drain is available, Resideo recommends a drum or disk humidifier instead.
The pressure switch mounts vertically with its pressure connectors facing down. Supply duct tubing goes to the + port and return duct tubing goes to the – port. You can use either port alone or both together. The H6062 humidistat can mount on the return duct, where wiring is easiest, or on a living space wall like a thermostat. Wiring follows the diagram in the humidifier manual, not the one packed with the humidistat. The red and white conductors can be swapped, and the NC terminal on the pressure switch is not used.
The separate HE360 Installation Kit uses an S688A sail switch and an H8908 humidity control. The sail switch has counterbalancing springs. Keep the "Down" spring for downward airflow and the "Up" spring for upward airflow, and remove both for horizontal ducts. The sail switch should go in the cold air return, because supply duct heat shortens the sail's life. The kit's self-piercing saddle valve should be installed with its handle pointing toward the ceiling so debris does not clog the solenoid's inline filter.
For daily use, an outdoor sensor lets the H6062 adjust humidity automatically and limit window condensation. Without the sensor, use the manual's chart: setting 15 at -20°F, rising to 40 above 20°F. Cooking, showering and drying clothes can push humidity too high. If these activities continue for several hours, turn the control to its lowest setting. Maintenance means cleaning mineral deposits from the tray, nozzle and drain hose, and replacing the pad with its marked end facing up. Never oil any part of the humidifier.
