Demand Response
Demand Response (DR) is a resource for balancing power supply and demand by
allowing consumers options to reduce or shift their energy consumption away from
peak periods.
How it works
• Enroll: Tenant or Property owner opt in to recieve DR events
• Integration with Aggregators: DR aggregators linked to the property’s utility
company integrate with APIs allowing automatic transmission of DR events to
thermostats
• Active DR Event Indicator: Thermostats display a distinctive icon alerting
tenants and guests a DR event has been sent
• Opt-Out Option: Tenants and Guests may opt out of DR events by adjusting
the setpoint
NOTE: DR requires rmware 1130 or later

Lighting Integration
The thermostat uses built-in infrared motion sensors in conjunction with a wired
occupancy sensor to scan a room for occupancy. An auxiliary output provides a
binary signal according to real-time occupancy status in the room.
The auxiliary output is wired to a 24VAC relay installed on the lighting circuit; closing
the circuit when the room is occupied, and automatically shutting o power to the
circuit after occupancy is no longer detected.
A RIB2401B relay is recommended.

“Automatic Fan Control Mode” - fan runs only when there
is a demand for heating or cooling;
“Manual Fan Control Mode” - guest can select between
automatic or continuous fan operation;
“Minimum Set point” - minimum temperature that a guest
can request;
“Maximum Set point” - maximum temperature that a guest
can request;
“Auto Changeover Set Point Oset” - the dierence
between the guest-selected set point and the heat and
cool changeover temperatures;
“1st Stage Dierential - Heat” - the temperature that
the thermostat has to sense between the automatic
changeover temperature for heat and the room
temperature before a call for the 1st stage heating is
initiated;
“2nd Stage Dierential - Heat” - dierence between 1st
stage heating temperature and room temperature before
the 2nd stage heating is initiated;
“1st Stage Dierential - Cool” - the temperature that
the thermostat has to sense between the automatic
changeover temperature for cool and the room
temperature before a call for the 1st stage cooling is
initiated;
“Forced 2nd Stage Heating” - number of minutes 1st
stage heating will run before 2nd stage heating is
automatically initiated if the guest set point is not reached
and the 2nd stage heating is not initiated through
dierential settings
“Temperature Recovery Time” - the maximum period of
time allowed for restoring the “Recovery Temperature”;
“Recovery Temperature” - the room temperature that
needs to be restored within the “Temperature Recovery
Time”;
“Maximum Setback Temperature” - the highest room
temperature allowed when thermostat is in the setback
mode;
“Minimum Setback Temperature” - the lowest room
temperature allowed when thermostat is in the setback
mode;
“Temperature Setback Delay” - the length of time for
which the room that is in the guest occupancy mode
needs to be unoccupied before the temperature setback
is initiated;
Incidental Occupancy Threshold - the minimum period
of time (in minutes) for which occupancy needs to be
detected in order to enter the “Guest Occupancy” mode;
Night Occupancy Threshold - the minimum period
of time during the Night Occupancy period for which
occupancy needs to be detected in order to enter the
Night Occupancy mode;
Night Occupancy Period - The period of time during the
day during which the Night Occupancy mode can be
activated if occupancy longer than the Night Occupancy
Threshold is detected;
“Auto Restore On” - thermostat will restore the most recent
guest settings when new occupancy is detected;
“Auto Restore O” - thermostat will NOT restore the most
recent guest and will remain turned o settings when new
occupancy is detected;
“Setback Set points On” - thermostat will maintain setback
temperatures when room is unoccupied;
“Setback Set points O” - thermostat will NOT maintain
setback temperatures when room is unoccupied;
“Incidental Occupancy” - occupancy shorter than the
Incidental Occupancy Threshold;
“Guest Occupancy” - occupancy longer than the
Incidental Occupancy Threshold;
“Temperature Setback” - thermostat maintains setback
temperatures and not the guest set point temperature in
order to save energy;
“Night Occupancy Mode” - thermostat status during
which setback mode is disabled if occupancy longer than
Night Occupancy Threshold is detected within the “Nigh
Occupancy” period;
“Automatic Temperature Changeover” - thermostat
automatically activates heating or cooling to maintain the
desired room temperature;
“External Thermostat” (Class 2) mode - HVAC unit setting
allowing it to be controlled by a remote thermostat;
