6. Trigger the pump to run by pressing the
Tool
button for two seconds to access the
configuration field. Then press the Tool
button three times to select the pump icon .
After selecting the pump, press the + button to
select ON.
7. Check the flow meters on the manifold and balance,
if required (see Step 8).
a. If a flow calculation is done, balance the loops
according to the calculation. (Proceed to Step 8.)
b. If a flow calculation is NOT done, as a starting
point, ensure all loops are completely open and
have flow. This will NOT balance your system;
however ensuring each loop has flow will ensure
heat is being delivered to each loop. Balance
the loops by monitoring the supply and return
temperatures for each loop and restricting flow
to bring the temperature differential to the
designed Delta T of the system.
Note: This is not the most accurate method for
loop balancing. Uponor always recommends a
heat and flow calculation for proper balancing of
the system.
8. Balance the loops.
a. Make sure the lock ring is lifted up and all loops
are fully open (turned counterclockwise).
b. Ensure water is flowing through the loops
(visible on the flow meters).
c. If needed, close the balancing valves to achieve
the desired flow.
d. After achieving desired setting(s), turn the lock
ring clockwise until the stop tab hits the setting
bar on the flow meter casing. Then, push down
to lock. Doing this locks the setting. If the loop
must be closed for some reason, it will not require
balancing when opening the loop — simply open
until reaching the lock-ring stop.
9. Configure boiler control with designed system
settings, making sure the temperature setting will
not damage the flooring.
10. Set thermostat(s) to desired setting.
11. Note all settings and gauge readings and
leave documentation with the unit.
12. Return pump delay back to desired setting by
pressing the Tool
button for two seconds
to access the configuration field. Then press the
Tool
button three times to select the
pump icon
.
13. Use
buttons to select the
desired setting.
