g)
Set the WHM system for desired mode of operation (Setpoint mode).
h)
Test the system completely with the ProtoNode installed.
8.8.2 Hardware Installation
All Innovation Hot Water Boilers that will be controlled by a WHM master must be equipped with
an actuator-controlled sequencing valve (P/N
92123
). If this valve is not already installed on the
cold water inlet, proceed as follows:
WHM Hardware Installation
1.
Remove the sequencing valve from its stowed location.
2.
Refer to Figure 8-2 and attach the valve to the cold water inlet of the unit (shown in Figure
8-2, below) using the pipe union and nipple provided.
3.
Ensure that the valve is positioned with the actuator enclosure position as shown in Figure
8-2.
4.
AERCO recommends that another pipe nipple and union be attached to the valve inlet
prior to connecting the cold water supply piping.
5.
Tighten all pipe connections after the sequencing valve is properly positioned.
6.
Connect the 4-pin Molex connector on the sequencing valve to the mating connector on
the Innovation harness at the rear of the unit.
7.
This completes the sequencing valve installation.
