DESCRIPTION
The HBX ORC-0100 is designed to be an energy-saving automatic control for
hot water boilers. The ORC-0100 measures the outside air temperature and
re-adjust the heating system water to a minimum water temperature to satisfy
the heat loss of the home or building.
Some features of the ORC-0100 are:
• Backlit graphic display
• Push button keypad control
• User-friendly programming features
• Includes external sensor
• Integrated 2 Amp dry contacts

PROGRAMMING ORC-0100
navigating the outDoor reset control
All programming steps within the outdoor reset
control are achieved by using the three buttons
(and combinations thereof) located on the right-
hand side of the thermostat.
The + button is used to scroll up in
menu screens and increase a value
within specic options.
The - button is used to scroll down in menu screens and decrease
a value within specic options.
Boiler aDjustment screen
Holding down the set button for 2 seconds while viewing the “Status Screen” will
take you into the “Adjustment Screen”.
Once you are in the desired options screen, use the +and -button to
scroll up and down. Press down the set button to choose the option
(the arrow to the left of your chosen option will turn black when you
have selected a specic step), then the +and -buttons to adjust the
value.
sPecial features
1) System pump pre-purge (30 seconds)
This will allow any residual heat to be taken out of the boiler before ring
the boiler. This feature is designed to reduce short cycling.
2) System Pump Post Purge (60 seconds)
After the heat demand has been satised, the system pump will stay on for
60 seconds. This will reduce a spike in temperature in the boiler when the
demand goes away.
3) DHW Priority (60 minutes)
This allows the user to select whether they would like the main system pump
to go off if there is a DHW demand. If priority is yes when there is a DHW call
and WWSD is on, the system pump will not come on.

Maximum Boiler Temperature
“Maximum Boiler Temperature” is used in the
outdoor reset design calculation, and also serves as
the maximum setting for the boiler.

Reduces the risk of condensing ue gases. It can run
with both condensing, and non-condensing boilers.

The “Outdoor Design Temperature” option should

Warm Weather Shutdown
“Warm Weather Shutdown” is the outdoor
temperature that must be reached for the control to
enter an energy-saving hibernation mode.

Domestic Hot Water Priority
This option will allow the DHW demand to override
the heating system for a max of 60mins in order
to satisfy the DHW demand. Once the control
switches to DHW priority, the DHW target will be the
Maximum Boiler Temperature. If after the 60mins
there is still an unsatised heat demand, the ORC-
0100 will automatically switch the system pump
back on to accommodate the call for heat. Once
the control switches to heat mode, the heat target
will be calculated based on the actual outside
temperature.
