Page 4: Critical Installation Information
Critical Installation Information Water Quality and Hardness Proper filtration is critical for the operation of the TrueSTEAM humidifier. Failure to address water quality can potentially lead to drastically increased maintenance requirements and premature failure of the TrueSTEAM humidifier and its components. Be sure to complete the following procedure well in advance of installation to ensure any additional costs are documented and understood. -
Page 5: Set The Automatic Flush Cycle Timing
If water hardness is in range 1: If water hardness is in range 2: M29661 M29602 Honeywell recommends using the RO Filtration Honeywell recommends using the system (sold separately). polyphosphate filter (sold separately). Note: If the RO Filtration System is not used, set the homeowner’s expectation that additional cleaning beyond once per season will be necessary. - Page 6 Use TrueSTEAM with water that is less than 1 grain per BEST gallon hardness. A properly functioning water softener will accomplish this. PRACTICE While the TrueSTEAM and its available filtration options help to address the issue of water quality and hardness, homes with extreme hard water problems should consider using a whole house water softener as the primary filtration device.

Page 7: Proper Sizing Of A Truesteam Humidifier
Proper Sizing of a TrueSTEAM Humidifier The Air-Conditioning, Heating and Refrigeration Institute (AHRI) has set guidelines for determining humidification capacity requirements. The recommendation is based on the square footage and type of home construction – assuming typical conditions. It is important to realize many homes will have humidification requirements that differ from the guidelines depending on how the circumstances differ from standard conditions. -
Page 8: Truesteam Pre-Install Information
In the event that a service technician needs to call in to the TrueSTEAM support techline, the following information is typically required for the Honeywell tech support specialist to accurately evaluate each situation. Failure to have this information ready may result in resolution delays or a potentially incomplete diagnosis. -

Page 30: Deciding On The Wiring Configuration
Deciding on the Wiring Configuration Before making decisions about wiring configurations: I understand when to use the DIP switches and how to set them for the humidity control. TrueSTEAM wiring is different from evaporative pad humidifier wiring. In addition to solenoid water valve actuation, TrueSTEAM can monitor system power and regulate system fan operation. - Page 31 IMPORTANT NOTE: This images below are not complete wiring diagram.

Page 47: Startup And Checkout
Startup and Checkout When installation is complete, plug TrueSTEAM in and turn the humidity control on. Make sure it is running properly before turning the system over to the homeowner. Once TrueSTEAM is running, day-to-day operation is hands-free, except for occasional cleaning. The homeowner can use the control to adjust the humidity setpoint, adjust the frost setting (if used), or turn TrueSTEAM off as desired. -
Page 48: Routine Maintenance
At the end of the cycle, TrueSTEAM refills the tank with fresh water and automatically returns to normal operation. Manual Cleaning Cycle Honeywell recommends that TrueSTEAM be manually cleaned and the water filter be changed at least once each humidification season. The manual cleaning is necessary to remove solid mineral deposits left behind during operation. - Page 49 BEST Perform all cleaning steps at least once per humidification season. PRACTICE CAUTION: Scalding hazard. • If you override the cooling action of the flush cycle, the tank will empty immediately, regardless of water temperature. Make sure the drain can handle up to 212°F (100°C) if you do this.
