KOOLMASTER PP-32
REV.01
EIGHT INDEPENDENT TEMPERATURE SENSOR INPUTS
Up to eight temperature sensors can be connected to the controller in order to
obtain a more accurate reading of the average room temperature and a faster
reaction time. Sensors may be assigned to each heater output or to auxiliary
outputs. Auxiliary outputs can be used to operate various devices such as
heating units or stir fans for instance.
OUTSIDE TEMPERATURE SENSOR
HUMIDITY COMPENSATION
Three mechanisms can be used to compensate for a high humidity level:
1. Fans' On-Time, in minimum vent. cycles, can automatically be increased.
2. Kool-Cel or mist units can be shutoff.
3. Heaters can be activated in timer mode.
STATIC PRESSURE & VENT DOORS & TUNNEL CURTAIN CONTROL
A static pressure input is provided to control static pressure by opening and
closing the vent doors and/or tunnel curtain.
CONTROL OF AIR INLET MOVEMENT
If the PP-32 is used in combination with one or more DWR-F-1A controllers,
the movement of air inlets can be coordinated with the operation of the fans
using a potentiometer located on the panel drive. This allows the air inlets to
be adjusted correctly, without the influence of uncontrollable factors such as
wind or air from adjoining rooms.
PASSWORD PROTECTION
A password can be enabled to restrict access to the controller setup functions.
BACKUP BATTERY
A backup battery allows the unit to keep time in case of a power failure.
OVERLOAD AND OVERVOLTAGE PROTECTION
Resettable fuses are provided at low-voltage inputs and outputs of the controller
to protect its circuitry in the case of an overload or overvoltage.
COMPUTER CONTROL
The controller can be connected to a computer, thus making it possible to
centralize the management of information and diversify control strategies.
TEST MODE
A test mode allows you to simulate temperature changes and verify controller
performance, as well as manually activate each output sequentially.
