- Page 5 20. Ensure that the chiller is set up according to the instructions before energizing. General Description The T255P is a solid-state thermoelectric heating and cooling system. The unit consists of a pump, fan, electrical circuitry, and a solid-state heat transfer assembly. The T255P maintains a set temperature of the working fluid that is circulated between the thermal management application and itself.
- Page 6 Setting up the Thermoelectric Unit Connect the unit to the application using a fluid transport from ThermoTek or hoses using Colder PLC or PLCD Insert fittings. Keep unit upright and on a level surface. Make sure there is a 6-inch clearance and free path for flow of air entry and exit around the chiller prior to operation.

- Page 23 RS232 Customer Interface General Description This document specifies an asynchronous, serial communication protocol to allow two devices to exchange data and control functions. These two devices are an IBM compatible Personal Computer (PC). Communications Settings The transmission rate is 9600 Baud, 8 data bits, no parity, 1 stop bit and XON / XOFF flow control.
- Page 24 1.3.2.1 Chiller Serial Watchdog Time-out If no communication occurs for a period greater than 10 seconds, then the chiller will take appropriate action, dependant on the state it was in when communications was lost. Stand By: The chiller will remain in stand by mode and transmit XON characters every 0.5 seconds until communication is re-established by receiving a SWC or a power-on reset.
- Page 25 Response Format Every command requires a response of some sort. The general form of the response is: command comm error n response checksum echo status Where sor - Start of Response. The command starts with a 23h representing an ASCII #.
- Page 26 Serial Watchdog Command and Response Format The serial watchdog command has a unique format. The command is in the form: command code checksum Where Start of Command. The command starts with a 2Eh representing an ASCII period. It is one byte in length command code The serial watchdog command is a single byte ASCII code 55h.
- Page 27 Chiller Status Indicates chiller status. Chiller OFF Chiller ON Dryer Status Indicates dryer status. Dryer OFF Dryer ON checksum Two ASCII hexadecimal bytes representing the least significant 8 bits of the sum of all preceding bytes of the command starting with sor. ASCII carriage return 0Dh 2.4.1 Example The PC would issue the following command:...
