[[I:05_HHt] and [I:06_HLt] are for changing
the heating high temperature range and low
temperaturerange.
You can change the Highest Set Temperature [I:05_
HHt] and the Lowest Set Temperature [I:06_HLt] by
adjusting the numbers on the display.
If [I:01_HCt]_“2:or” is selected then the settings
for [I:05_HHt] and [I:06_HLt] will beoverridden by
[I:02_tHS] settings. (except below)
If [I:02_tHS]_“7:CU” is selected then the settings
for [I:05_HHt] will be the heating hightemperature
range and [I:06_HLt] will be heating low
temperature range.
[I:09_EPP (External Pump)]
(page 51)
1 sec.
This setting can activate or deactivate the
terminals in the Combi Boiler for an External Pump
(secondary pump) on the circuit board.
settings:
OFF (When an external pump is not used.),
ON (When an external pump is used.)
(Default setting =
OFF
)
[I:07_bSt (Boost Timing)]
1 sec.
NOTE When [I:01_HCt] setting is “2:or” or
“3:EC”, this function will appear.
This setting is to increase the set temperature
during unit cold start up if the actual room
temperature doesn’t reach the thermostat set
temperature quick enough, the Boost time
function will increase the set temperature of the
Combi Boiler by 10°F (5°C) after the selected Boost
time setting has passed.
Example:
Room thermostat set at 72°F, Combi Boiler set
temp at 140°F, and Boost time function set
to 30 min.
If the room temperature does not reach 72°F
within 30 min then the Combi Boiler will
increase its set temp from 140°F to 150°F.
settings:
OFF (Boost Timing is deactivated.),
1 - 120 min (Time before starting the boost
operation.)
(Default setting =
OFF
)
[I:08_Air (Air Handler)]
(page 51)
1 sec.
This function needs to be turned “on” if an Air
Handler is being used as a heating type.
The Air Handler function is designed to stop the
Air Handler’s pump and fan operation when the
Combi Boiler’s operation is not suitable for the Air
Handler.
settings:
OFF (When an air handler is not used.),
ON (When an air handler is used.)
(Default setting =
OFF
)
