4.1 Electric Heating Element Status Indicator Light
This
indicator light will illuminate GREEN whenever the Hydro-Hot's 120
VAC Electric Heating Element is operating and providing heat to the Hydro-
Hot's Boiler Tank, reference Figure 5. Please note that this light will only be
active if the Electric switch is in the ON position, reference Figure 4. If this
indicator
light illuminates RED, it indicates an electrical overload condition
(i.e. short) has occurred in the Electric Heating Element's VDC powered
circuitry.
4.2 Heating Zones Status Indicator Lights
These
five indicator lights (separately) will illuminate GREEN whenever a
Zone Thermostat, for each particular zone, is calling for heat, reference
Figure 5. The GREEN indicator lights also indicate that VDC power is being
supplied to the particular interior heating zone's Heat Exchangers (i.e. fan
motors). If any of the five indicator lights illuminate RED, it indicates that an
electrical overload condition (i.e. short) has occurred in a particular heating
zone's circuitry.
NOTE:
A short in either a heating zone's Thermostat or a heating zone's
Heat Exchanger circuit, will cause the indicator light to illuminate RED.
