Sequence of Operation - CMD
CMD – Cooling Only
the cMd cooling only unit is designed to maintain the desired set point temperature within a conditioned space by switching and modulating via the programmable microprocessor, controlling the unit in one of five occupied modes:
1. free cooling – using outside air
2. dX cooling stage 1 – mechanical cooling with 67% compressor, low speed fan, minimum fresh air
3. dX cooling stage 2 – mechanical cooling with 100% compressor, low speed fan, minimum fresh air (this is a dehumidification stage, used in conjunction with hgRh option)
4. dX cooling stage 3 – mechanical cooling with 100% compressor, high speed fan, minimum fresh air
5. heating (optional) – room return air and minimum fresh air these modes are switched based on the following parameters: return air temperature, supply air temperature and the ambient air temperature.
Mechanical Cooling (All Stages)
If the return air temperature is higher than the occupied set point and if the ambient air temperature is high enough the unit will call for mechanical dX cooling. the microprocessor controller will determine which stage of mechanical cooling is most efficient to handle the cooling load based on the return air, supply air, and ambient air temperatures, and pre-engineered control strategies. the microprocessor controller will then place the unit in one of the three stages of mechanical cooling.
1. Stage one utilizes 67% compressor capacity and a low speed supply fan
2. Stage two utilizes 100% compressor capacity and a low speed supply fan
3. Stage three utilizes 100% compressor capacity and a high speed supply fan.
Free Cooling
If the return air temperature is higher than the occupied set point and if the ambient air temperature is low enough to satisfy the cooling load in the occupied space, the microprocessor controller will signal the fresh air economizer damper. this will automatically modulate between 0-100% and the conditioned space temperature will be maintained by full fresh air or “free cooling”. during free cooling the outdoor fan will operate at reduced speed to match supply air volume.
On units equipped with energy recovery but no economizer, energy wheel is de-energized and outdoor air ventilation fan is
100% energized to allow up to 500cfm of outdoor air.
On units equipped with energy recovery and economizer but with no return air damper, energy wheel is de-energized and outdoor air ventilation fan is 100% energized. economizer damper will automatically modulate between 0-100% allowing up to 75% free cooling to maintain conditioned space temperature.
On units equipped with energy recovery and economizer and return air damper, energy wheel is de-energized and outdoor air ventilation fan is 100% energized. economizer damper and return air damper will automatically modulate between 0-100% allowing up to 100% free cooling to maintain conditioned space temperature. the free cooling mode of operation leads to much reduced running time for the compressor leading to cost and equipment savings.
Ventilation
during occupied cooling or heating modes, economizer damper or outdoor air ventilation fan can be set to achieve the necessary amount of outside air to be introduced prior to being conditioned, thus satisfying minimum ventilation code requirements.
Hot Gas Reheat (Optional)
during a call for dehumidification from return air humidity sensor, hgRh valve is opened and unit enters second stage of mechanical cooling. Outdoor air fan may modulate to maintain proper reheat capacity. hgRh valve will close when return air humidity falls below set point or when other modes of cooling are required.
Heating (Optional)
as standard, this unit is not fitted with any heating capability; however, optional electric, hot water or steam heating may be provided and will be energized if the return air temperature falls below the occupied set point.

Sequence of Operation – CMP
CMP – Cooling & Heating
the cMp heat pump unit is designed to maintain the desired set point temperature within a conditioned space by switching and modulating via the programmable microprocessor, controlling the unit in one of seven occupied modes:
1. free cooling – using outside air
2. dX cooling stage 1 – mechanical cooling with 67% compressor, low speed fan, minimum fresh air
3. dX cooling stage 2 – mechanical cooling with 100% compressor, low speed fan, minimum fresh air (this is a dehumidification stage, used in conjunction with hgRh option)
4. dX cooling stage 3 – mechanical cooling with 100% compressor, high speed fan, minimum fresh air
5. dX heating stage 1 – reverse cycle with 67% compressor, low speed supply fan, and minimum fresh air
6. dX heating stage 2 – reverse cycle with 100% compressor, high speed supply fan, and minimum fresh air
7. heating (optional) – room return air and minimum fresh air these modes are switched based on the following parameters: return air temperature, supply air temperature and the ambient air temperature.
Free Cooling
If the return air temperature is higher than the occupied set point and if the ambient air temperature is low enough to satisfy the cooling load in the occupied space, the microprocessor controller will signal the fresh air economizer damper. this will automatically modulate between 0-100% and the conditioned space temperature will be maintained by full fresh air or “free cooling”. during free cooling the outdoor fan will operate at reduced speed to match supply air volume.
On units equipped with energy recovery but no economizer, energy wheel is de-energized and outdoor air ventilation fan is
100% energized to allow up to 500cfm of outdoor air.
On units equipped with energy recovery and economizer but with no return air damper, energy wheel is de-energized and outdoor air ventilation fan is 100% energized. economizer damper will automatically modulate between 0-100% allowing up to 75% free cooling to maintain conditioned space temperature.

3. Stage three utilizes 100% compressor capacity and a high speed supply fan.
Heating (All Stages)
If the return air temperature is below the set point and the ambient air temperature is high enough (the heat pump will be locked out at 28°f ambient), the microprocessor controller will de-energize the reversing valve allowing the unit to operate in the reverse cycle dX heating mode. the microprocessor controller will also determine which stage of dX heating is most efficient to handle the heating load based on pre-engineered control strategies and the return air, supply air, and ambient air temperatures. the microprocessor controller will then place the unit in one of two dX heating stages of operation.
1. dX heating stage one utilizes 67% compressor capacity and a low speed supply fan
2. dX heating stage two utilizes 100% compressor capacity and high speed supply fan.
3. Optional hot water, steam, or first stage of electric heat.
Note: if electric heat is capable of two stages, the second stage
will be utilized for emergency backup only. during periods of operation in low ambient temperature, the unit will periodically enter into a defrost mode to remove the frost build up on the coil acting as the evaporator. the microprocessor controller will de-energize the outdoor fan and energize the reversing valve allowing the unit to operate in the cooling mode using hot refrigerant to melt the frost build up. defrost cycle will end when outdoor coil sensor is satisfied or when microprocessor defrost time limit expires, whichever comes first. an alternate heating source e.g. optional electric or hot water heating should be provided and will be energized to offset the cooling effect of the defrost cycle.
Ventilation
during occupied cooling or heating modes, economizer damper or outdoor air ventilation fan can be set to achieve the necessary amount of outside air to be introduced prior to being conditioned, thus satisfying minimum ventilation code requirements.
Hot Gas Reheat (Optional)
during a call for dehumidification from return air humidity sensor, hgRh valve is opened and unit enters second stage of mechanical cooling. Outdoor air fan may modulate to maintain proper reheat capacity.
