Can I install a humidifier on this system?

Yes, a humidifier can be installed on a Daikin DMVE Series system. The system has accessory terminals that support humidification functionality with three operational modes: ON (enabled during a heat call with active humidification request), OFF (humidifier remains off), and IND (humidifier operates independently with any humidification call).

How to check static pressure

User image 67d066dde580f

Mr. Anderson
March 11, 2025

To check static pressure for the Daikin DMVE Series:

1. Measure Return Air Static Pressure in inches of water column (IN. W.C.).
2. Measure Supply Air Static Pressure in inches of water column (IN. W.C.).
3. Ignore +/- from the readings, then add the total to determine Total External Static Pressure.

Ensure proper system operation by verifying:
- Secure EEV and EEV wiring.
- Proper wire routing without rubbing.
- Proper drainage.
- Tight blower wheel screws.
- Correct factory wiring and connections.
- Proper clearances as per installation instructions.
