Honeywell 5000 Series Instruction Sheet

APPLICATION
The V7335A "5000" series electric modulating regulator
(Moduplus®), when installed on VK41../VK81.. series gas
controls, expands their application versatility and provides
the following extra functions:
• Servo pressure regulation
Outlet pressure is held at a constant value regardless of
fluctuations of input pressure.
• Modulating control
Between minimum and maximum outlet pressure gas
supply to the appliance is dependent on the electrical
signal to modulating coil.
• Mechanical limitation of outlet pressure
The minimum and maximum burner pressures are
mechanically adjusted to guarantee good burner
performance in case the modulating control should
become out of range.
The Moduplus® is designed to work together with the W4115
logic control, T7335A thermistor temperature sensor and an
advanced range of micro computer based modulating
controls.

V7335A "5000" series
SPECIFICATIONS
In general the specifications of the VK41../VK81.. gas
controls are valid. See instruction sheet EN1R-9162
However the following information is deviating and replaces
therefore the relevant information of that instruction sheet.
Model
Gas controls:
Suffix M: fast opening with electric modulating regulator.
Suffix N: slow opening with electric modulating regulator.
Electric modulating regulator:
V7335A low voltage (Moduplus®)

Electrical connection
The Moduplus® is provided with quick connect 2.8 x 0.8 mm
terminals which are suitable for appropiate receptacles.
Pressure feedback connection
The Moduplus® has a nipple with 6 mm outer diameter for
connection between regulator and combustion chamber of
appliance.
Maximum operating pressure
The P indication on the housing of the gas control is the
max.
maximum pressure at which the gas control functions safely.
However the maximum operating pressure is limited by the
pressure range of the Moduplus® concerned.
60 mbar for pressure range 1 ... 25mbar / 1 ... 37 mbar
