TESTING THE SYSTEM
Prior Steps
It is imperative that all previous tasks have been
completed before testing or operating the system.
f
Use of Construction Mode to test the boiler and flow
rates on each loop
f
Disable Construction Mode by removing the jumper
from the appropriate sensor port
f
Successful installation of all electrical components
(Manifold Controllers, actuators, thermostats)
Once these steps have been completed sequentially,
proceed to the next steps.
Testing the Controls
With all components installed, it’s time to test each
zone independently to ensure the thermostats are
accurately controlling each zone.
To begin, go to the Zone 1 thermostat, then follow
the instructions below.
f
Tap the thermostat screen
f
Next, tap the button in the lower right corner
and choose “Tutorial” to familiarize yourself with
the controls
f
Once complete, go to “Settings” then ”Support”
and tap ”Test Zone”
f
Go to the manifold cabinet for this zone. On the
Manifold Controller you will see a green light on the
loops requesting a call for heat
f
After 5 minutes, the green lights will turn blue,
indicating that the actuators have opened and water
is flowing to the zone
f
If something does not appear to be working properly,
consult your Warmboard Engineered Drawings
f
After 15 minutes, the test will end
f
Repeat this process for each thermostat
Final Checklist
f
A flame icon will appear on the thermostat when
there is a call for heat. It will take 5-7 minutes for the
boiler and pump(s) to receive this signal and fire up
f
When receiving a call for heat, lights on the pump(s)
will engage and water will begin to circulate.
If not, reference the pump installation manual
f
When there is a call for heat, water temperatures on
the boiler LCD should read between 90–140˚F
f
Match the specifications in the Warmboard Design
Drawings for each loop and zone to ensure the
system operates smoothly
f
Confirm the Warmboard-supplied tubing labels are
adhered to each loop to accurately identify each loop
and zone from inside the manifold cabinet
NOTE
: Warmboard thermostats have an “Off”
setting of 55˚F for freeze protection.
Make sure all supply and return tubing labels
have been affixed to the appropriate loop at the
manifold location.
After a zone calls for heat, the actuators will
take approximately 5 minutes to open and begin
heat flow.
