ClimateMaster Water-Source Heat Pumps
Console (CCE) Series
0.5 to 1.5 Ton Console Units
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 (either CXM or DXM) 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)
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 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
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 overfl ow 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)
