Note: To achieve full benefi t of the two-stage compressor and ECM fan, a 2 Heat/2 Cool thermostat (or a 3 Heat/2 Cool
thermostat when electric backup heat is required) should be employed.
This control system coupled with a multi-stage thermostat will better dehumidify room air by automatically running the heat pump’s
fan at lower speed on the fi rst stage of cooling thereby implementing low sensible heat ratio cooling. On the need for higher cooling
performance the system will activate the second stage of cooling and automatically switch the fan to the higher fan speed setting. This
system may be further enhanced with a humidistat. Units not having automatic low sensible heat ratio cooling will not be accepted;
as an alternate a hot gas reheat coil may be provided with control system for automatic activation.
Digital Night Setback with Pump Restart (With ATP32U03/04 or ATC32U01 T-stat)
The unit will be provided with a Digital Night Setback feature using an accessory relay on the DXM2 controller and an external, fi eld-
provided time clock. The external time clock will initiate and terminate the night setback period. The thermostat will have a night setback
override feature with a programmable override time period.
An additional accessory relay on the unit DXM2 controller will energize the building loop pump control for the duration of the override
period. (Note: this feature requires additional low voltage wiring. Consult Application Drawings for details.)
Remote Service Sentinel:
Solid state control system shall communicate with thermostat to display (at the thermostat) the unit status, fault status, and
specifi c fault condition, as well as retrieve previously stored fault that caused unit shutdown. The Remote Service Sentinel allows
building maintenance personnel or service personnel to diagnose unit from the wall thermostat. The control board shall provide a
signal to the thermostat fault light, indicating a lockout. Upon cycling the G (fan) input 3 times within a 60 second time period, the
fault light shall display the specifi c code as indicated by a sequence of fl ashes. A detailed fl ashing code shall be provided at the
thermostat LED to display unit status and specifi c fault status such as over/under voltage fault, high pressure fault, low pressure
fault, low water temperature fault, condensate overfl ow fault, etc. Units that do not provide this remote service sentinel shall
not be acceptable.
Option: Lonworks interface system
Units shall have all the features listed above and the control board will be supplied with a LONWORKS interface board, which is
LONMark certifi ed. This will permit all units to be daisy chained via a 2-wire twisted pair shielded cable. The following points must
be available at a central or remote computer location:
a. space temperature
b. leaving water temperature
c. discharge air temperature
d. command of space temperature setpoint
e. cooling status
f. heating status
g. low temperature sensor alarm
h. low pressure sensor alarm
i. high pressure switch alarm
j. condensate sensor alarm
k. hi/low voltage alarm
l. fan “ON/AUTO” position of space thermostat as specifi ed above
m. unoccupied/occupied command
n. cooling command
o. heating command
p. fan “ON/AUTO” command
q. fault reset command
r. itemized fault code revealing reason for specifi c shutdown fault (any one of 7)
Option: MPC (Multiple Protocol Control) interface system
Units shall have all the features listed above and the control board will be supplied with a Multiple Protocol interface board.
Available protocols are BACnet MS/TP, Modbus, or Johnson Controls N2. The choice of protocol shall be fi eld selectable/
changeable via the use of a simple selector switch. Protocol selection shall not require any additional programming or special
external hardware or software tools. This will permit all units to be daisy chain connected by a 2-wire twisted pair shielded
cable. The following points must be available at a central or remote computer location:
a. space temperature
b. leaving water temperature
