must be HDPE (High Density Polyethylene) to avoid thermal cycling shock stress failure over the lifetime of the unit. Drain pan
shall be fully insulated. Drain outlet shall be located at pan as to allow unobstructed drainage of condensate. Drain outlet for
horizontal units shall be connected from pan directly to FPT fi tting. No hidden internal tubing extensions from pan outlet
extending to unit casing (that can create drainage problems) will be accepted. The unit as standard will be supplied with
solid-state electronic condensate overfl ow protection. Mechanical fl oat switches will NOT be accepted.
Option: The drain pan shall be constructed of 304 stainless steel.
Electrical:
A control box shall be located within the unit compressor compartment and shall contain a75 VA transformer, 24 volt activated,
2 or 3 pole compressor contactor, terminal block for thermostat wiring and solid-state controller for complete unit operation.
Reversing valve and fan motor wiring shall be routed through this electronic controller. Units shall be name-plated for use with
time delay fuses or HACR circuit breakers. Unit controls shall be 24 Volt and provide heating or cooling as required by the remote
thermostat/sensor.
Solid State Control System (DXM2):
Units shall have a solid-state control system. Units utilizing electro-mechanical control shall not be acceptable. The control
system microprocessor board shall be specifi cally designed to protect against building electrical system noise contamination, EMI,
and RFI interference. The control system shall have the following features:
• Anti-short cycle time delay on compressor operation.
• Random start on power up mode.
• Low voltage protection.
• High voltage protection.
• Unit shutdown on high or low refrigerant pressures.
• Unit shutdown on low water temperature.
• Condensate overfl ow electronic protection.
• Option to reset unit at thermostat or disconnect.
• Automatic intelligent reset. Unit shall automatically reset the unit 5 minutes after trip if the fault has cleared. If a fault occurs 3
times sequentially without thermostat meeting temperature, then lockout requiring manual reset will occur.
• Ability to defeat time delays for servicing.
• Light emitting diode (LED) on circuit board to indicate high pressure, low pressure, low voltage, high voltage, low water/air
temperature cut-out, condensate overfl ow, and control voltage status.
• The low-pressure switch shall not be monitored for the fi rst 120 seconds after a compressor start command to prevent nuisance
safety trips.
• 24V output to cycle a motorized water valve or other device with compressor contactor.
• Unit Performance Sentinel (UPS). The UPS warns when the heat pump is running ineffi ciently.
• Water coil low temperature sensing (selectable for water or antifreeze).
• Air coil low temperature sensing.
• Removable thermostat connector.
• Night setback control.
• Random start on return from night setback.
• Minimized reversing valve operation (Unit control logic shall only switch the reversing valve when cooling is demanded for the
fi rst time. The reversing valve shall be held in this position until the fi rst call for heating, ensuring quiet operation and increased
valve life.).
• Override temperature control with 2-hour timer for room occupant to override setback temperature at the thermostat.
• Dry contact night setback output for digital night setback thermostats.
• Ability to work with heat pump (Y, O) or heat/cool (Y, W) type thermostats.
• Ability to work with heat pump thermostats using O or B reversing valve control.
• Emergency shutdown contacts.
• Boilerless system heat control at low loop water temperature.
• Ability to allow up to 3 units to be controlled by one thermostat.
• Relay to operate an external damper.
• Ability to automatically change fan speed from multistage thermostat.
• Relay to start system pump.
• 75 VA control transformer. Control transformer shall have load side short circuit and overload protection via a built in circuit
breaker.
NOTE: Units not providing the 8 safety protections of anti-short cycle, low voltage, high voltage, high refrigerant pressure,
low pressure (loss of charge), air coil low temperature cut-out, water coil low temperature cut-out, and condensate
overfl ow protections will not be accepted.
