Temperature Sensor - T8800 Series
These products are all Made to Order
Which means they are non-cancelable and non-refundable
The T8800 Sensor is a single sensor programmable temperature monitoring security device. The T8800 has only one sensor. The single temperature sensor is housed in the appliance (T8800) or can be ordered with a connected remote probe (T8800R). The memory in the T8800 is non-volatile because all temp trip limits are set with a small screw driver. No typical software program is required. Simple to set.
Connect DC power to terminals 1 (+) and 2 (-). Observe polarity. WARNING. If you are using a power supply other than the RTD/12 (GRI PN# 8065), be certain that the power is regulated. The use of unapproved power supplies will void the warranty. GRI’s technical support team can provide information. Call 800-445-5218.
There are two (2) jumpers in the T8800. JP1 is used to direct programming to the high/low limits thresholds. JP2 converts the unit from Celsius to Fahrenheit. JP1 has multiple pins for the jumper during set up. With the center pin used as the center of a clock, place the jumper at 12 o’clock to adjust the High Limit. Place the jumper at 6 o’clock to adjust the Low Limit. Placing the jumper at the 3 o’clock position is for standard operating of the device.
There are three (3) adjustable pots (potentiometers) with the T8800. R19 on the far left side of the T8800 is used to adjust the temperature baseline for the unit. This control can be used to bring the T8800 in the same range of operation as other temperature sensors in the same room.

There also is a mounting pattern template provided with the printed instructions. Route wires to the device as necessary from behind the T8800. Remember, it is important to avoid lights, motors, ballast transformers, fans and electromagnetic devices when routing and pulling wires to this device.
