DHW Recirculation with Timer Relay Input
This parameter is available when DIP switch 3 is
in the ON position. This enables an external
13
timer to also control the timing for DWH
recirculation to more directly correspond to the
customers needs.
CH Temperature Limitation During
Simultaneous Operation
This parameter is available when DIP switch 3 or
4 is in the ON position.
This enables the CH temperature setting to be
limited during simultaneous DHW and CH
operation. This can prevent unintentionally
14
supplying high temperature DHW to low
temperature CH applications.
During simultaneous operation, supply
temperature may be up to 180°F. When
selecting "NO" limitation, ensure that the CH
system and heating application is designed for
this temperature.
3 Way Valve Position During Simultaneous
Operation
This parameter is available when DIP switch 3 or
4 is in the ON position.
15
This adjusts the 3 Way Valve position to open
the CH side more for when the flow of the CH
side is reduced due to DHW demand. This may
restrict the DHW capacity.
LC Check
This setting enables the boiler to check for lime
scale conditions in the DHW side of the plate
16
heat exchanger. When detecting lime scale, an
LC error code will appear on the display. Once
lime scale is removed by flushing the plate heat
exchanger, the LC code will disappear.
Adjust DHW Temperature Setting
This setting enables the DHW output
17
temperature to be adjusted without adjusting
the set point temperature.
