COOLING –HEATING CONTROLLER Model VD1T
ATTENTION Firmware V3
Read carefully these instructions before installing and using this device and keep them for future reference. Attention to installation and electrical wiring. Use this device
only as described in this document and never use itself as a security device. The device must be disposed of in accordance with local standards for the collection of
electrical and electronic equipment.
DESCRIPTION
VD1T is a temperature controller for cooling –heating applications as well as food drying applications (eg sausages). The room temperature is controlled with an NTC /
PTC sensor. The evaporator sensor input through parameters can adjusted act as a door switch to control the room door. It has an automatic conventional defrost or
smart defrost function for energy saving and better control of the defrost process. It has 3 indication digits of temperature display with an accuracy of 0.5 ° C and 4
buttons. It has a relay 16A 250VAC that through parameters adjusted in operation: cooling or heating or heating with countdown. It has a buzzer that activates in case of
alarm. The device is mounted on a panel hole 29x71mm and it is restrained with plastic side brackets. Through the serial input it can be connected to a network either
through Cloud IoT on the CORTEX platform, or through a local computer in the CAMIN program for complete local recording and monitoring of the device.

VD1T connects via serial input to the cloud and the online CORTEX platform or to a local computer with the CAMIN program or to the memory key or to the Mini Logger or to
any Modbus network.
CAMIN program: local connection and monitoring - recording and management of the thermostat through the CAMIN program installed on a local computer.
Mini Logger recorder: The thermostat can be connected to the recorder and record based on selected minutes on a microSD memory card, its temperatures and the
state of the relays and alarms. It is connected via a cable to the serial input and we program the parameter Add = 1.
Memory key: the parameter values are stored in the memory key or recorded by it in the thermostat.
When the parameter rHC = 2, the relay operates in heating mode based on the parameter Hod while “SET”is displayed. By pressing the relay is activated and the
indication “rUn” is displayed. By pressing we see successively the temperature of the second sensor, if it is activated, as well as the remaining time. When time elapses,
the relay is deactivated and “End” is displayed on screen. By pressing again, the procedure starts over. The thermostat constantly controls the relay based on the adjusted
Set Point (SPo). If SPo changes during “rUn”, automatically the control of the relay is adjusted. If timer “Hod”changes during “rUn”mode, it will not change until the next
running cycle.
SMART DEFROST
Smart defrost function: The thermostat finds the ideal operating temperature of the evaporator and if the evaporator operates at a temperature lower than the ideal temperature
constant dSt than the ideal, and for a time longer than the time constant dS1, defrost begins.
Smart defrosting works in parallel and independently of conventional defrosting. It is automatic and the thermostat decides when to defrost and for how long. It is necessary
to connect the evaporator sensor and set the parameter 8, SOI = 0. The two types of defrosts - smart and conventional - can operate simultaneously based on the respective
settings. By enabling smart defrosting, the conventional defrost can be set to operate safely - for example one defrost every 48 hours. This time is renewed each time an
automatic defrost is performed.
Activate the smart defrost from parameter 24, dSE = 1. It is recommended to start the refrigerator, to make a defrost cycle, where it is activated with parameter 25, dSb = 1.
The time constants dS1 and temperature dSt are formed based on the image of the element: if we observe ice, we reduce the constants.
ELECTRICAL DIAGRAM - DIMENSIONS
ATTENTION: according to safety standards, the device must be properly positioned and protected from any contact with electrical parts. The device must be fastened in such a way that it
cannot be removed without the use of tools. Disconnect the main safety switch of the installation before proceeding to any maintenance. Disconnect the power supply of the device before
proceeding to any maintenance. Do not place the device near heat sources, equipment containing strong magnets, in areas affected by direct sunlight or rain. Prevent electrostatic discharges
and sharp objects from been inserted to the device. Separate signal cables from power supply cables to prevent electromagnetic disorders. Signal cables must never be in the same pipe with
the power supply cables. ATTENTION: Read carefully the technical specifications and make sure that the working conditions are appropriate. According to safety standards, the device must
be fastened in such a way that it cannot be removed without the use of tools
Dimensions are in mm. The device is mounted on panel hole with cut 29x71mm and restrained with plastic side brackets
