mars 7602-457 Communicating Programmable Thermostat Instruction Manual
Installation Manual - 7602-457 Communicating, Programmable Thermostat
NOTE 1: The Proportional Integral options require first stage
6.0 Humidity Configuration
heating or cooling to be active for a minimum of 5 minutes,
before energizing second stage when configured for multi
stage operation.
Configure humidity control settings (dehumidification/
humidification).
NOTE 2: The Differential option will activate first stage heating
or cooling when the temperature is more than the first stage
differential value (User Manual section 5.6.2.3), below or
above the setpoint. Second stage heating or cooling will be
activated when the temperature is more than the first and
second stage differential values combined (User Manual
section 5.6.2.3), below or above the setpoint. Third stage
heating will be activated when the temperature is more than
the first, second, and third stage differential values combined
(User Manual section 5.6.2.3), below the setpoint.
Adjust the Humidity Control settings using the up/down arrow
buttons. Press the center button to save changes.

Dehumidification – This logic will communicate
a Dehumidification output when the humidity is
greater than the setpoint (acts as a dehumidistat).
The Dehumidification output will not be
communicated when the humidity is below the
setpoint.
Humidification – This logic will communicate a
Humidification output when the humidity is less
than the setpoint (acts as a humidistat). When the
Humidification output is active, the fan output will
also be active. The Humidification output will not
be communicated when the humidity is above the
setpoint.
7.2
ANTICIPATOR
If you find that the thermostat is overshooting or
undershooting the temperature setpoint value, the Anticipator
setting allows for adjustment to correct the temperature
algorithm. When the Anticipator value is set to a lower
number, the thermostat becomes more sensitive and when
the Anticipator value is raised, the thermostat becomes less
sensitive. If the thermostat is overshooting the temperature
setpoint, adjust the Anticipator value up to reduce thermostat
sensitivity. If the thermostat is undershooting the temperature
setpoint, adjust the Anticipator value down to increase
thermostat sensitivity.

•
Both – Incorporates both Dehumidification and
Humidification logic.
None (default) – Dehumidification
and Humidification outputs will not be
communicated.

ELECTRIC HEAT LOCKOUT
The Differential adjustment will vary the number of degrees
from the setpoint before a call for heating or cooling is made.
Use this function if you find that the thermostat is starting a
call too soon/late or staging equipment up/down too quickly/
slowly. For example, with a 1 ˚F 1st stage differential and
a heating setpoint of 70˚F, your thermostat will not call for
heating until the temperature is 69˚F.

TEMPERATURE CONTROL
Adjust the Differential setting using the up/down arrow
buttons. Navigate between Differentials using the left/right
arrow buttons. Press the center button to save changes.
Configure the logic the thermostat uses to meet the
temperature setpoints.

Proportional Integral (default) – This logic will
use a combination of temperature differential and
operating time to determine the appropriate heating
or cooling stages for operation (see NOTE 1).
Proportional Integral (No Down Staging) – This
logic includes the Proportional Integral logic, but
in addition the logic keeps all active heating or
cooling stages energized until the demand is fully
satisfied (see NOTE 1).
Differential – This logic will only use temperature
differential to determine the appropriate heating or
cooling stages for operation. This logic will keep
all active heating or cooling stages energized until
the demand is fully satisfied (see NOTE 2).
7.4 CYCLES PER HOUR
The thermostat allows the user to adjust the maximum
number of on/off cycles per hour to maintain the desired
indoor temperature.
Adjust the Cycles per Hour setting using the up/down arrow
buttons. Press the center button to save changes.
•
4 (default): operation will start no sooner than 15
minutes after the previous call was initiated
6: operation will start no sooner than 10 minutes
after the previous call was initiated (can provide
tighter temperature control)
