WARMBOARD COMFORT SYSTEM // ELECTRIC
CONSTRUCTION MODE
Once the system is filled properly with water,
put Warmsource-E in “Construction Mode”, an
operating state that supplies heat to the structure
BEFORE
thermostats, Manifold Controller(s) and
actuators are installed. Construction Mode offers
the opportunity to listen for air noises while
confirming all loops are operating with the proper
flow rates and water temperatures. Activating the
system also brings heat to cold working conditions
and helps hasten the release of moisture from various
materials, including paint, plaster, hardwood flooring
and other wood materials.
f
Step 1
: Set the temperature gauge on the cover
of Warmsource-E to 102˚F
f
Step 2
: Open the front cover
f
Step 3
: Locate the Smart Reset Controller (SRC),
then plug the white Construction Mode jumper into
the “Sensor 2” terminal. The boiler temperature
can be adjusted if a higher temperature is desired
(Warmsource-E will reach the target temperature
in about 10 minutes)
f
Step 4
: Ensure Warmsource-E is hardwired to
the 240 VAC
f
Step 5
: Close the front cover, and flip the two
electrical breakers to power up the unit
f
Step 6
:
Return to each manifold and adjust the flow
rates of each loop
1
Unthread and (discard) the white caps from
the return side of the manifold
2
Remove the red caps on the supply side of the
manifold and adjust the black knobs beneath.
Flow rates for each loop should be equal to,
or greater than, those noted in the WCS Design
Drawings. When done, replace the red caps
DO NOT
use Construction Mode after any
actuators have been installed.
Connect Warmsource to an appliance timer to
limit the hours the system runs in Construction
Mode and reduce energy use. Be sure to remove
before installing thermostats and actuators.
