HUMIDITROL DEHUMIDIFICATION® SYSTEM
Factory installed option designed to control humidity.
Provides dehumidification on demand using American Society of Heating, Refrigeration and Air
Conditioning Engineers (ASHRAE)
90.1 recommended method for comfort conditioning humidity control.
Unit comes equipped with one row reheat coil, solenoid valve and humidity controller.
In addition to a thermostat or room sensor used for conventional operation, a humidity sensor is required and must be located in the occupied space. Remote
Mounted Humidity Sensor Kit is required for field installation.
The humidity sensor provides input to the Unit Controller which is used to control activation of the dehumidification operation.
Reheat controls are located in the compressor control section of the unit for easy access.
Benefits
Improves indoor air quality.
Helps prevents damage due to high humidity levels.
Improves comfort levels by reducing space humidity levels.
OPERATION
No Dehumidification Demand
The unit will operate conventionally whenever there is a demand for cooling or heating and no dehumidification demand.
Free cooling is only permitted when there is no demand for dehumidification.
Dehumidification Demand Only
The Unit Controller is factory set at 60% relative humidity setpoint and can be adjusted at the Unit
Controller or with optional Unit
Controller Software.
Reheat operation will initiate on a dehumidification demand and does not require a cooling demand.
The unit will operate in the dehumidification mode until the relative humidity of the conditioned space is below the setpoint.

The reheat coil is sized to provide
20°C to 24°C supply air during reheat operation.
This reduces sensible cooling capacity and extends compressor run time to control humidity when the cooling load is low.
A solenoid valve diverts hot gas from the compressor to the reheat coil.
The cooled and dehumidified air from the evaporator is reheated as it passes through the reheat coil.
The de-superheated and partially condensed refrigerant continues to the outdoor condenser coil where condensing is completed. The unit will continue to operate in this mode until the dehumidification demand is satisfied.
See Sequence of Operation for additional information.
Dehumidification and Cooling
Demand (Thermostat/Room
Sensor Application)
Two-stage compressor models (036, 048, 060)
If both a dehumidification and a Y1 cooling demand occur, the system will operate in the full cooling mode at first stage indoor air flow. If a
Y2 cooling demand occurs along with a dehumidification demand, the system operates in full cooling mode at full cooling airflow until the Y2 cooling demand is satisfied.
Then the system will revert to the dehumidification mode if a dehumidification mode demand is present.
Single speed compressor model (072H)
If both a dehumidification and a cooling demand occur, the system will operate in cooling until the cooling demand is satisfied. Then the system will energize the dehumidification mode.

SEQUENCE OF OPERATION
Objective: Outline the unit functions as a result of room thermostat or zone sensor demands.
Given: When economizer is present, it will function as initial part of the unit cooling system. When not present, unit will function as if outdoor ambient is high and sensed as not suitable.
BELT DRIVE SYSTEM OPERATION (036 THROUGH 060 MODELS):
Modulating Outdoor Air Damper:
Damper minimum positions #1 and 2 are adjusted during unit setup to provide minimum fresh air requirements at the indicated supply fan speeds per American Society of Heating, Refrigeration, and Air Conditioning Engineers (ASHRAE)
62.1.
• Supply fan is off and the outdoor air damper is closed
• Supply fan is on low speed and the outdoor air damper is at minimum position 1
• Supply fan is on high speed and the outdoor air damper is at minimum position 2
1
Unit Features an Economizer and Outdoor Air is Suitable
Cooling - Thermostat or Zone Sensor Mode (Up to 3 stages Y1, Y2, Y3)
Y1 demand:
1 st
: Compressor is off, supply fan is on low speed, economizer modulates (minimum to maximum open position) to maintain 13°C supply air temperature (default unit controller setting)
2 nd
: After 5 minutes (default unit controller setting), supply fan switches to high speed. Economizer continues modulating with supply fan on high speed to maintain 13°C supply air temperature
Y2 demand:
1 st
: Compressor is off, supply fan is on high speed, and economizer modulates to maintain 13°C supply air temperature
2 nd
: Economizer opens to maximum. If economizer stays at maximum open for 3 minutes (default unit controller setting) compressor is energized and operates at first stage while supply fan stays on high speed
1
Outdoor air suitability is determined by the energy state of outdoor ambient (enthalpy or sensible) and its ability to achieve the desired free cooling effects. Outdoor air suitability can also be determined by a third party controller and provided to the rooftop unit (RTU) via a network connection.
Y3 demand:
1 st
: Economizer is at maximum open and compressor operates at first stage. If economizer stays at maximum open for 3 minutes (default unit controller setting) compressor switches to second stage operation while supply fan stays on high speed
Unit Does not Feature an Economizer (or Outdoor Air Is Not Suitable)
Cooling - Thermostat or Zone Sensor (Up to 2 stages Y1, Y2)
Y1 demand:
1 st
: Compressor operates at first stage and supply fan operates at low speed
