I am installing a Neptronic SK 300 Humidifier in a printing room at a plant.
It is the bacnet model and uses a HRO 20 Humidistat/Wall controller.
I am having to do both humidification and dehumidification for the room and have no experience in setting up control strategies for either.
Our plan is to let the HRO 20 do the control and just monitor the room for the graphics etc using the bacnet.
Its a honeywell system...jace.....and Im using a spyder to control the air handler and condensing units.
Im fine with letting the humidifier control the humidity. This is a plant, the air handler is always on and the humidifier has safeties to prevent it from running with no airflow and there is also a high humidity safety in the supply duct.
Right now Ive got some logic in the spyder to control dehumidification using a wall mounted zio with space temp and a humidity sensor. Im letting a pid control the cooling based on humidity and a heat pid working off the space temp to maintain the space temp.
What Im wondering is if I can use the Neptronic SRO 20 humidistat to control dehumidification also.
The HRO 20 instructions show a dehumidification analog output and a dehumidification binary output.
The instructions give no clue how to set up and use these two outputs but Im thinking I can use the SRO dehumidification output to solely control my condensers..... there will be no cooling pid whatsoever and the only heating/cooling logic in my spyder will be a heat pid to maintain space temp.
Does this sound reasonable ???
Ive also considered using the SRO to control dehumidification but also putting in my own cooling pid in the spyder and using the SRO 20 dehumidify BO to enable and disable the cooling pid....... this way...in times when they might need cooling but not dehumidification.....the cooling can work.
I dont see the above scenario occuring.....but the logic would be there just in case.
Any helpfull feedback would be appreciated.
