Control Actions
There are two types of heating control output: Modulating (0~10 VDC) and On/ Off (SPDT
relay). Both will output simultaneously.
1. Modulating Type Heating Control:
(1) Output Voltage: Valve output allow minimum adjustment (
AO1 Low(E5)
) from 0-2 Vdc and maximum
adjustment (
AO1 High(E6)
) from 8 to 10 Vdc. These two output voltages can be gauged by multimeter during
setting to reflect the setting change effects.
(2) Reverse Output: The output voltage can be reversed by setting
rE-H(E18)
to 0(Direct) or 1(Reverse).
(2) When Demand for Heating, a “Running ( Gear) (
)
” icon will be shown on the LCD.
