INSTALLATION
Q7300 Subbase with Remote-Mounted
Temperature Sensor(s)
When Installing this Product…
If only the remote-mounted temperature sensor(s) is used to
sense and control room temperature, then install the
thermostat in an area that is accessible for setting and
adjusting the temperature and settings.
1. Read these instructions carefully. Failure to follow the
instructions can damage the product or cause a
hazardous condition.
2. Check the ratings given in the instructions and on the
product to make sure the product is suitable for your
application.
3. Installer must be a trained, experienced service
technician.
4. After completing installation, use these instructions to
check out the product operation.
If both the subbase and remote-mounted temperature
sensor(s) are used to sense and control room temperature,
then install the subbase about 5 ft above the floor in an area
with good air circulation.
Install the remote-mounted sensor(s) about 5 ft (1.5m) above
the floor in an area with good air circulation at average
temperature. See Fig. 2.
Location
Do not mount the sensor(s) where it can be affected by:
— drafts, or dead spots behind doors and in corners.
— hot or cold air from ducts.
— radiant heat from sun or appliances.
— concealed pipes and chimneys.
— unheated (uncooled) areas such as an outside wall
behind the thermostat.
T7200 Wallplate or Q7300 Subbase without RemoteMounted Temperature Sensor
Install the thermostat about 5 ft (1.5m) above the floor in an
area with good air circulation at average temperature. See
Fig. 2.
Do not install the thermostat where it can be affected by:
— drafts, or dead spots behind doors and in corners.
— hot or cold air from ducts.
— radiant heat from sun or appliances.
— concealed pipes and chimneys.
— unheated (uncooled) areas such as an outside wall
behind the thermostat.
If more than one remote sensor are required, they must be
arranged in a temperature averaging network consisting of
two, three, four, five or nine sensors. See Fig. 3 through 7.
NOTES:
— When sensor averaging, the T7147A can be substituted
for the T7047C. The T7147A includes OVERRIDE and

IMPORTANT
To avoid electrical interference, which can cause
erratic performances, keep wiring runs as short as
possible and do not run thermostat wires adjacent to
the line voltage electrical distribution systems. Use
shielded cable (Belden type 8762 or equivalent for
2-wire and Belden type 8772 or equivalent for 3-wire).
The cable shield must be grounded only at the
controlled equipment case.

The T7200/T7300 contains three switching relays. In
conventional applications, the relays control first stage cooling,
first stage heating, and fan. In heat pump applications, the
relays control the heat pump compressor, auxiliary heat, and
the fan. Because of this change in switching logic, it is
important to use Q7300C,D, H2003, H2011 Subbases when
the T7300 is set for heat pump applications and the Q7300A,G,
H2029 Subbases when the T7300 is set for conventional

P+I Control
The T7200/T7300 microprocessor based control requires that
the user understands temperature control and thermostat
performance. A conventional electromechanical or electronic
thermostat does not control temperature precisely at setpoint.
Typically, there is an offset (droop) in the control point as the
system load changes. This is a phenomenon that most people
in the industry know and accept. Many factors contribute to
offset including switch differential, thermal lag, overshoot,
cycle rates and system load.

The thermostat microprocessor simultaneously gathers,
compares and computes data. Using this data, it controls a
wide variety of functions. The special proprietary algorithm

T7200D,E, T7300D,E,F AND Q7300 SERIES 2000 PROGRAMMABLE COMMERCIAL THERMOSTATS AND SUBBASES
(program) in the thermostat eliminates the factors causing
offset. This makes temperature control more accurate than
the conventional electromechanical or electronic thermostats.
The temperature control algorithm is called proportional plus
integral (P+I) control.
Occupied Operation
When the thermostat is operating in the Occupied period, the
temperature is controlled to the occupied heat or cool
setpoint. The normally open (A1 ) auxiliary relay contacts are
closed and the normally closed (A3) auxiliary relay contacts
are opened during the Occupied periods (if the subbase
being used has this option). The fan operates as follows: fan
selection can be set to On (always energized) or Auto (cycles
with Y1 or W1).
The thermostat sensor, located on the thermostat or remote,
senses the current space temperature. The proportional error
is calculated by comparing the sensed temperature to the
programmed setpoint. The deviation from the setpoint is the
proportional error.
Unoccupied Operation
When the thermostat is operating in the Unoccupied period,
the temperature is controlled to the Unoccupied heat or cool
setpoint. The normally open (A1) relay contact is open and
the normally closed (A3) relay contact is closed. The fan
operates as follows: fan is always intermittent (cycles with Y1
or W1).
The thermostat also determines integral error, which is a
deviation based on the length of error time. The sum of the
two errors is the (P+I) error. The cycle rate used to reach and
maintain the setpoint temperature is computed using the P+I.
The addition of the integral error is what differentiates the
thermostat from many other electronic and electromechanical
Intelligent Recovery® Feature
THERMOSTAT
COOL SETPOINT
Intelligent Recovery® feature is a Honeywell trademark for
the way the thermostat controls the heating and cooling
equipment during recovery from Unoccupied to Occupied
setting. During recovery, the control point changes gradually
rather than jumping from the energy saving setting to the
comfort setting all at once.

P+I CONTROL POINT
When the Intelligent Recovery® feature is used in heating,
the control point raises gradually, maximizing the use of the
more economical first stage heat to bring the sensed
temperature to the desired comfort setpoint. This minimizes
using the typically more expensive second-stage heat.

The advantages are:
• Comfort setting is achieved at the programmed time and
maintained regardless of weather conditions; occupants
are comfortable.
• Drafts from low temperature discharge air are minimized
during occupied periods.
• Thermostat automatically uses the more economical first
stage of heat as the primary heat source during recovery,
avoiding the use of the expensive second stage heating.
• Comfort and energy savings can be achieved in both
heating and cooling.
• The thermostat reduces heat cycling, extending
equipment life.

Fig 17. Proportional temperature control

Equipment Protection
As part of the operational sequence, the T7200/T7300
microprocessor also incorporates minimum on and off times
for all heating and cooling stages. Minimum on time is set in
the installer setup number 32. Using the minimum on and off
times assures that rapid cycling of equipment does not occur,
which extends equipment life. Minimum on and off times are
set in the Installer Setup.
Recovery from Unoccupied
The heating heat pump recovery ramp is 3°F (1.6°C) per
hour, which differs from the 5°F (2.8°C) per hour for
conventional systems. The 3°F helps the system use the
economical heat pump more and the expensive auxiliary heat
less. The cooling ramp is 5°F, the same as for conventional
systems.
T7200/T7300 Thermostat Operation
Startup
When power to the thermostat is turned on, a startup and
initialization program begins. The startup occurs only on initial
powerup. After total loss of power for an extended period, the
current time and day may need to be set, but the user
program is held. The initial default values are heating 68°F
(20°C) and cooling 78°F (26°C) for the Occupied periods.
Unoccupied default values are heating 55°F (13°C) and
cooling 90°F (32°C).
Conventional System
The T7200 and T7300D,F Thermostats with Q7300A,G,H
Subbases are designed for conventional heat/cool applications.
Heat Pump Operation
The T7200E and T7300E,F Thermostats with Q7300C,D,H
Subbases are used for heat pump applications. Additional
information is required when configured for heat pump

Subbase Auxiliary Relay
O and B Terminals for Heating or Cooling Changeover
The Q7300C controls heat pump changeover. The Q7300D,H
is only used in a heat pump application when the heat pump
controls the reversing valve changeover. See Table 13 for the
operation of the O and B terminals on the Q7300C, H2003.
The Q7300 Auxiliary Relay output acts as a time-of-day
switch to be used with an economizer minimum position
control. The normally open (A1) auxiliary relay contacts are
closed during the Occupied period and open during the
Unoccupied period. The normally closed (A3) auxiliary relay
contacts are open during the Occupied period and closed
during the Unoccupied period. The contacts are in the normal
state during recovery.
O and B Terminals on a Conventional Subbase
Conventional subbase O and B terminals can be used to
drive dampers and valves. The O terminal is energized on a
call for cooling and the B terminal is energized on a call for
heating.

Mechanical cooling is often used when outside
temperatures are in the 50°F (10°C) to 60°F (16°C) range
and humidity is below 50 percent. In central and northern
climates, hundreds of hours fall into this temperature
category. By permitting 80 to 100 percent outside air into the
system, mechanical cooling may not be needed at all,
particularly during Spring and Fall.
An economizer is used to take advantage of the outside air.
The typical economizer consists of an outside air damper,
motor, outdoor air changeover control and a minimum
position potentiometer. The motor controls the dampers.
Suitability of the outside air for cooling is determined by the
outdoor air changeover control. The potentiometer is used for
adjusting the minimum position of the economizer dampers,
which provide a minimum amount of fresh air for ventilation.
a
When the system is calling for heat or is de-energized, but
the last function was heat.
b
When the system is calling for cool or is de-energized, but
the last function was cool.
c
When the last function was heating, the operation is the
same as Auto (Heat). If the last function was cooling, the
operation is the same as Auto (Cool).
The economizer reduces compressor run time, thereby saving
energy and extending the compressor life. The drawback to
using the economizer is that during the Unoccupied period, if
there is no call for cooling or outdoor air is not suitable for free
cooling, the economizer is controlled to minimum position. This
position allows some percentage of outdoor air to enter the
building, regardless of air suitability. The situation can cause
the heating or cooling to run more often than if suitable outdoor
air is permitted to enter the building.
Fan Operation
When the fan is set to On, the fan is energized continuously in
the Occupied period. The Auto setting energizes the fan with
the heating or cooling system. If the subbase is Q7300D, the
fan cycles with Y1 and W1 during Unoccupied period.
Emergency Heat
When the system is set for Em Heat (on select T7300
Thermostats), the auxiliary heat is stage one and the
compressor stages are locked off. The fan cycles with the
auxiliary heat.
The thermostat can take advantage of an economizer by
connecting the auxiliary relay contacts (A1 and A2) of the
subbase to control the economizer minimum position
potentiometer. The contacts close during the Occupied
period, allowing the economizer to operate normally. The
contacts are open during the Unoccupied period, disabling
the minimum position feature of the economizer. The open
contacts cause the economizer to drive dampers fully closed
instead of staying at minimum open position. This reduces the
possibility of unsuitable outdoor air from entering the building,
which lowers the internal load on the HVAC system and saves
additional energy.
Communicating Subbase
Select T7300F Thermostats with the Q7300H Communicating
Subbase are designed for conventional or heat pump
applications in a LonWorks® network. The Q7300H Subbase
allows remote access and the sharing of clock, schedule,
setpoints, bypass and other system parameters in a
LonWorks® network. See fig. 32 for a T7300F/Q7300H wiring
layout in a LonWorks® network.
Other Uses for the Auxiliary Relay
GENERAL OPERATION INFORMATION
Examples of other uses of the auxiliary relay are hot water
heaters, lighting or baseboard heat. The additional loads are
connected to the auxiliary relay contacts on the subbase. The
contacts are rated for 1.6A at 30 Vac, but can be adapted to
higher current applications with the use of an external relay
and transformer. See Fig. 18.
Cycle Rates
The thermostat control algorithm maintains the temperature
by cycling stages of heating or cooling to meet setpoint.
