INSTALLER MENU SEQUENCE
DHW SETTINGS
Hold Button:
MENU/<System Settings>/<DHW Settings>
•
A DHW call can be initiated by shorting the DHW input terminals, 33 and 34. In addition,
using a Heat-Timer temperature sensor on the same terminals instead of a dry-contact
input will add the DHW Set Point and Differential control capability.
•
On a DHW call, the SQ-Elite-8T will raise the Target to either 200ºF or the Maximum
Target, which ever is lower.
•
The SQ-Elite-8T provides three levels of DHW pump operation. The first is when Primary/
Secondary is selected as the DHW Piping from the Startup Menu on page 28. This option
will provide no DHW Priority. And, if there was a DHW call during the Summer or when
the outdoor temperature is above the Outdoor Cutoff, both the DHW Pump and the
System relays will energize. Upon the termination of the DHW call, the DHW Pump relay
will de-energize leaving the System relay energized for the Run-On delay.
•
If Parallel was selected as the DHW Piping from the Startup menu on page 28 and the
Season was set to Winter while the DHW Priority Timer was set to NO, a DHW call will
keep the System relay energized in addition to energizing the DHW Pump relay. Upon
termination of the DHW call, the DHW Pump relay will de-energize leaving the System
relay on.
•
However, in Winter, if the DHW Priority Timer was set to a value other than NO, a DHW
call will de-energize the System relay and energize the DHW Pump relay. This will remain
for the period of the DHW Priority Timer setting or until the DHW call terminates,
whichever is sooner. If the DHW call was still active after the DHW Priority Timer elapses,
the System relay will energize for the remaining of the DHW call period.

DHW PIPING)
Adjustable NO, 1 to 120 minutes

•
The DHW Priority Timer is only available when DHW Piping is set to Parallel (See page 28).
It provides the user with the capability of selecting the DHW Priority period. If NO was
selected, a DHW call will energize the DHW pump relay without affecting the System
Pump operation. That is, when in Summer or Outdoor Cutoff, a DHW call will energize
only the DHW Pump relay leaving the System relay off.
•
In Winter, if the DHW Priority Timer was set to a value other than NO, a DHW call when
the outdoor temperature is below the
•
Outdoor Cutoff will cause the System relay to de-energize and the DHW Pump relay
to energize for the period of the DHW Priority Timer or until the DHW call expertise,
whichever happens sooner. If the DHW call did not expire within the Priority period,
then the System relay will energize.
