a 3 Way Valve and the boiler pump are to be

Only 120 VAC 3 Way Valves may be used in this

*This parameters is available when Indirect
Tank "In Use" is selected on DIP switch 3 and
when "Use Pump" is selected in Parameter 32.
This selects the operaon of the indirect tank
heang by priority or simultaneously with CH.
When "Indirect Tank Priority" is selected, other
pumps except for the indirect tank pump will
not operate while the tank is being heated.
When "Simultaneous Heang with Indirect Tank
and CH", all pumps may operate simultaneously.
When in Simultaneous mode, if the tank does
not achieve the Indirect Tank Setpoint
Temperature within 60 minutes, it will transion
to Indirect Tank Priority.

*This parameters is available when Indirect
Tank "In Use" is selected on DIP switch 3. This
selects the me that the indirect tank will
maintain priority. Aer this period of me
passes, the indirect tank will cease to be heated
and central heang will have priority. If there is
sll an indirect tank demand aer 60 minutes
passes of CH priority, indirect tank priority will
begin again.

CH Temperature Limitaon to Allow
Simultaneous Operaon with Indirect Tank
Yes No
*This parameters is available when Indirect
Tank "In Use" is selected on DIP switch 3 and
when "Use Pump" is selected in Parameter 32
and also when selecng "Simultaneous Heang
with Indirect Tank and CH" in Parameter 33.
This enables CH seng limitaon during
simultaneous heang. This can prevent
unintenonally supplying high temperature
supply water to low water heang temperature
applicaons such as oor heang. During
simultaneous operaon, the heang supply
temperature is based on the indirect tank
supply temperature. When "NO" is selected,
make sure that the CH system and heang
applicaon is designed to allow for the high
supply temperature.
