Section 1.2 - Adjusting the Temperature
To adjust the system temperature higher, stop any hot water fl ow,
and press the Up Button until you reach the desired temperature
setting. See Figure 1.2.a.
NOTE: The temperature can only be raised above 112ºF if the water
fl ow has been stopped, this is a safety feature of the system.
For temperature settings above 120ºF see the instructions in Sec-
tion 1.5 to increase the max temperature range.
Manifold System Operation

Section 1.3 - Status Lights
The status lights on the remote consist of a “Burner On” indicator,
see Figure 1.3, and a Priority light.
The “Burner On” indicator will come on to show when only when the
system is heating water. This is regardless of the number of units
operating in the system.
The “Priority” light tells which remote control has priority over the
system in applications with multiple remote controls. This feature is
only available on single installation residential units.
