Honeywell International Inc. RV8310 Manuale Utente

DRAFT

 RT8220A is a transmitter to be used with the RV8310D receiver/valve.

The RF millivolt system consists of a RV8310D receiver/valve, RT8220A transmitter,
and a pilot burner with two Q313 thermopiles.

The RV8310D is flame powered with two thermopiles, and has flame powered
modulation, line powered fan modulation, and a quick dropout function of 30 seconds or
less with loss of pilot flame.

The receiver has a manual switch. If the switch is in the REMOTE mode and the pilot is
lit, the RT8220A transmitter can control the main valve, flame modulation, fan control,
and set temperature. If the switch is in the LOCAL mode and the pilot is lit, the valve will
be at the highest fixed pressure setting and the RT8220A transmitter cannot turn off the
main burner. The RT8220A will control the fan but not the flame modulation.

The pilotstat knob in the valve portion of the control provides for the OFF mode for the
RV8310D. When the pilotstat knob is rotated to the OFF position, the pilot and main
valve are turned off and the RT8220A transmitter provides no control.

The valve portion of the control has a pilotstat, pilot adjustment, European style inlet and
outlet pressure taps, 7/16-24 UNS pilot connection, and 3/8” NPT inlet and outlet
connections. The capacity is 60,000 BTUH at 1” p.d..

The regulator is dedicated natural gas or LP. The receiver/valve is rated at 175 F. If the
ambient temperature rises above 185 F, the output pressure is reduced until the ambient
temperature drops below 175F.

1.  Use only on a vented appliance.
2.  Turn off the gas supply at the appliance service valve before starting the installation,

and perform a Gas Leak Test after the installation is complete.
