FUNCTION DESCRIPTION ENTRY RANGE DEFAULT
HEAT CIRCUIT 1 & 2 Sub-Menus
The Sub-Menu Functions for HEAT CIRCUIT
1 & HEAT CIRCUIT 2 are identical. The
Function values in this Sub-Menu level will
change, depending on the Heat Circuit
Function (HC FUNCTION) selected.
HC FUNCTION
Heat Circuit Function defines type of circuit:
00 = Standard Heat Circuit
01 = Control to fixed flow temperature
02 = Swimming pool control (HC 2 ONLY)
03 = Hot Water Circuit
04 = Return flow temp. increase via mixing
valve.
00 – 04
00
(Standard
Heat
Circuit)
PUMP MODE
Circulation pump mode control for ON/OFF
switching of pumps.
00 = Standard pump control
01 = Pump switching per heating limits
02 = Pump switching per heating program
03 = Continuous pump operation
00 - 03 00
MIXER OPEN
(NOT for HW
circuit)
Specifies speed setting at which mixer motor
opens when there is a control temperature
difference.Entering small temperature
difference values may cause the mixing valve
to oscillate
5°F -25°F 18°F
MIXER CLOSE
(NOT for HW
circuit)
Specifies speed setting at which mixing valve
closes when there is a control temperature
difference.
Entering small temperature difference values
may cause the mixing valve to oscillate
5°F -25°F 12°F
MAX T-FLOW
Maximum allowable water temperature setting
for the heating circuit.
68°F – 230°F 176°F
MIN T-FLOW
Minimum allowable water temperature setting
for the heat circuit.
50°F – 230°F 50°F
FROST PROT
Specifies the minimum allowable outside air
temperature setting for the Frost Protection
Mode. If temperature drops below this value,
the system switches to the Frost Protect
Mode and the pumps are switched ON.
-5°F – 41°F 32°F
OUT-TEMP-DEL
Outside Temperature Delay. Specifies the
elapsed time before a decrease in the outside
temperature will affect the indoor room
temperature. The time entered must be
consistent with the type of building
construction (i.e., thick well-insulated walls
can use a long time delay. For light, poorly
insulated structures, set time to 0 hours)
0:00 – 24:00
0:0
(N/A)
SLOPE OFFSET Heating slope distance. 32°F – 194°F
48°F
