Belimo and RTC Modulating System
and DFC+ Integrated Gas Fired Heating
control
This system is made up of 3main components,
a variable gas valve or regulator, a discharge
air temperature sensor, and an amplifier
(DFC+) to control them all.
The discharge air temp sensor is mounted in an
air mixing tube, located near the discharge air
side of the heater. Its function is to provide
temperature information to the amplifier
(DFC+). This information is used by the
amplifier to control the “MAX” air temp portion
of the amplifier.
The Belimo or RTC Modulating System
provides for continuous, steady heat, at the
rate required. It does not stop the heater at any
time.
The modulator is the device that does the
actual increasing and decreasing of gas flow to
the burner. An electromagnet controls how
much gas can pass through the modulator. The
more voltage that is applied to the magnet, the
more gas that can pass through. The modulator
is typically full open when a voltage of about
24-volts DC is applied from the amplifier.
Minimum flame results from zero volts DC.
The
DF1600 heater has a minimum BTU input
rating of 324538 BTUs on NG (81782 Kcal)
and 326289
BTUs (
82223 Kcal) on LP
.
The Belimo Modulating System has been
pre-set at the factory to insure this input.
No field adjustment of this set point is
required.
Conventional Remote Thermostat
The optional remote thermostat (if used)
connects to the remote thermostat receptacle
on the heater. The difference is that when this
device is used, the heater delivers a constant
high temperature which is set on the SP of the
RTC DFC+ Controller, until the set temperature
on the conventional thermostat is reached. At
that time, the heater goes to 120
°
F and keeps
the temperature balanced until the temperature
at the thermostat falls below the set
temperature. The heater then goes back to the
thermostat mode delivers high temperature air.
To use this device, select and position the
thermostat at a location that will represent a
good average room temperature inside the
structure to be heated that will not be directly
affected by the heated air discharge from the
heater. Route the plug end of the cord to the
heater and plug into the special receptacle
located on the heater control panel.
T
he thermostat assembly comes with a 50-foot
cord with a plug, as standard.
The adjustment range is from 40° to 110° F. (5°
to 43° C.). To use the thermostat, plug in the
remote thermostat to the designated REMOTE
STAT receptacle then dial up or down or setting
it to the desired room temperature to be
maintained.
MAINTENANCE
WARNING
For your own safety, Lockout electrical
power before attempting any service
procedures to prevent accidental start-up.
