Page ______ of ______
h. Ability to work with heat pump thermostats using O or B reversing valve control.
i. Emergency shutdown contacts.
j. Boilerless system heat control at low loop water temperature.
k. Ability to allow up to 3 units to be controlled by one thermostat.
l. Relay to operate an external damper.
m. Ability to automatically change fan speed from multistage thermostat.
n. Relay to start system pump.
o. 75 VA control transformer. Control transformer shall have load side short circuit and overload protection via a built in circuit breaker.
Digital Night Setback with Pump Restart (DXM w/ ATP32U03/04)
The unit will be provided with a Digital Night Setback feature using an accessory relay on the DXM controller with an ATP32U03/04
thermostat and an external, 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 DXM 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 (CXM/DXM):
Solid state control system shall communicate with thermostat to display (at the thermostat) the unit status, fault status, and speci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 specic code as indicated by a sequence of ashes. A detailed ashing code shall be provided at the thermostat
LED to display unit status and specic fault status such as over/under voltage fault, high pressure fault, low pressure fault, low water
temperature fault, condensate over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 (either CXM or DXM) and the control board will be supplied with a LONWORKS
interface board, which is LONMark certi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 speci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 specic shutdown fault (any one of 7)
This option also provides the upgraded 75VA control transformer with load side short circuit and overload protection via a built in
circuit breaker.
Option: MPC (Multiple Protocol Control) interface system
Units shall have all the features listed above (either CXM or DXM) 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 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:
