an area with good air circulation at average temperature.
See Fig. 2.
IMPORTANT
or remote-mounted sensor.
To avoid electrical interference, which can cause
erratic performances, keep wiring runs as short as
possible and do not run thermostat wires a dja ce nt 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.
Q7300 Subbase with Remote-Mounted
Temperature Sensor(s)
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.
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.
If multiple remote sensors are required, they must be
arranged in a temperature averaging network consisting of
two, three, four, five or nine sensors. See Fig. 3 through 8.
NOTES:
— When sensor averaging, the T7147A can be substituted
— Up to four T7147As can be used in parallel to place the
for the T7047C. The T7147A includes OVERRIDE and
WARMER/COOLER keys.

OPERATION
T7200/T7300 Relay Logic
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 a Q7300C,D,
Q7300H2003, or Q7300H2011 Subbase when the T7300 is
set for heat pump applications and a Q7300A,G,
Q7300H2029 Subbase when the T7300 is set for
conventional applications.
The T7200D Relay Logic is for conventional applications.
The T7200E Relay Logic is for heat pump applications.

T7200/T7300 and Conventional Thermo stats
P+I Control
The T7200/T7300 micro processo r based con trol requires that
the user understands temperature control and thermostat
performance. A conventional electromechanical or electronic
thermostat does not co ntro l temperature precisely at s etpoint.
Typically, there is an offset (droop) in the control point as the
system load chang es. This is a phen omenon th at most p eople
in the industry know and accept. Many factors contribute to
offset including switch differential, th ermal lag, ov ershoot,
T7200/T7300 Thermostat Operation
Startup
When power to the thermostat is turned on, a startup and
initialization prog ram be gins. T he sta rtup oc curs on ly on initia l
powerup. After total loss of power for an extended peri od , 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).
cycle rates and system load.
NOTE: The thermostat controls to the Unoccupied default
The thermostat microprocessor simultaneously gathers,
compares and computes data. Using this data, it controls a
setpoints of 55°F (1 3°C) for he at and 90°F (3 2°C) for
cool when no program is set.
wide variety of functions. The special proprietary algorithm
(program) in the thermostat eliminates the factors causing
offset. This makes temperature control more accurate than
the conventional electromechanical or elec tro nic the rmo stats.
The temperature control algorithm is called proportional plus
integral (P+I) control.
The thermostat sensor, located on the thermostat or remote,
senses the current space temperature. The proportional error
is calculated by comparing the sensed temperature t o the
programmed setpoint. The deviation from the setpoint is the
Occupied Operation
When the thermostat is operating in the Occu pi ed peri od,
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 Occu pied period s (if the subba se being
used has this option). The fan operates as follows: fan
selection can be set to On (alway s energized) or Auto (cycles
with Y1 or W1).
proportional error.
Unoccupied Operation
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 el ec tron ic and elec tro me cha ni cal
thermostats. See Fig. 18.

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.
63-4355—420
When the thermostat is operating in the Unoccu pie d perio d,
the temperature is controlled to the Unoccupied heat or cool
setpoint. The normally open (A1) relay conta ct is open and the
normally closed (A3) relay contac t is closed. The fa n o perates
as follows: fan is always intermittent (cycles with Y1 or W1).
Intelligent Recovery® Feature
Intelligent Recovery is a Honeywell trademarked feature
for the way the thermostat controls heating and cooling
equipment during recovery from the Unoccupied to Occupied
setting. During recovery, the control point changes gradually
rather than shifting immediat ely from the ene rgy savi ng
setting to the comfort setting.
When Intelligent Recovery is used in he ating, the co ntrol point
raises gradually, maximizing the use of the more economical
first stage heat to br ing the sens ed tem perature to the desire d
comfort setpoint. This minimizes using the typically more
expensive second-s tag e heat.
Advantages of Intelligent Recov ery 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.
• The more economical first stage of he at is the primary heat
source during recovery, minimizing use of the expensive
second-stage heat.
• Comfort and energy savings can be achieved in both
heating and cooling.
• Heat cycling reduced, extend in g equi pm ent life .
RECOVERY FROM UNOCCUPIED
The heat pump heat recovery ramp is 3°F (1.6°C) per hour.
This differs from the 5°F (2.8°C) per hour for conventi onal
systems. The 3°F helps the system use the economical heat
pump more and the expensiv e auxili ary heat less . The cooli ng
ramp is 5°F, the same as for conventional systems.

Subbase Auxiliary Relay
The Q7300 Auxiliary R elay output ac ts as a time-o f-day switch
to be used with an eco nom izer m in im um pos iti on con trol. 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 pe riod and c losed duri ng the Un occupie d
period. The contacts are in the normal state during recovery.
Interfacing with Electromechanical
Economizers (Subbases with Auxiliary Relay)
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, ou tdoor air changeov er control and a mini mum 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.
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 cool 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 cooli ng to run mo re ofte n than if suitable
outdoor air is permitted to enter the building.
The thermostat can take advantage of an economizer by
connecting the subbase auxiliary relay contacts (A1 and A2)
to control the economizer minimum position potentiometer.
The contacts close during the Occupied period, allowing the
economizer to ope rate norma lly. The contacts open during the
Unoccupied period, disabling the minimum position feature of
the economizer. The open contacts cause the economizer to
drive dampers fully cl osed instead of staying at min imum 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.
Other Uses for the Auxiliary Relay
Examples of other uses of the auxiliary relay are hot wate r
heaters, lighting or baseboard heat. The additional loads are
connected to the aux il iar y re lay co ntacts on the subbase. Th e
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. 19.
