Humidity Sensor - H8800 Series

These products are all Made to Order Which means they are non-cancelable and non-refundable Description Humidity Sensor The Humidity Sensor is a single sensor programmable humidity monitoring security device. Unlike it’s 1st cousin, the T8800, used for temperature sensing, the H8800 has one sensor to detect and report relative humidity. The single humidity sensor is housed in the appliance (H8800) or it can be ordered with a remote probe (H8800R). The memory in the H8800 is non-volatile. Connection 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. There are two (2) jumpers in the H8800. JP1 is used to direct programming to the high/low limit humidity thresholds. 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’c
