Description

The M326A-2Z Temperature/Moisture Activator operate by detecting environmental conditions through a base mounted temperature sensor and a heated precipitation sensor. When rain or snow land on the precipitation sensor the traces are bridged and a closure is detected. The heater then rapidly evaporates the moisture, clearing the sensor. The sensor for the M326A-2Z Temperature/Moisture Activator simply screws into the top of the controller enclosure.

These signals are then supplied to the microcontroller. Depending on the way the user has configured the sensor the microcontroller determines the appropriate action to perform. For example, the M326A-2Z contains two 30-amp control relays along with an exterior switch for changing from manual/automatic/standby modes.

The difference between “sensor” and “controller” modes is the “Delay Off” drying cycle provided by each configuration. “Delay Off” time is the amount of time the sensor/controller will hold the load control relay(s) closed after the last detection of rain or snow. Proper setting of “Delay Off” assures that pavement or roofs not only melt but also dry, reducing the chance for dangerous refreezing of water left behind. A sensor is used to activate an external control unit when rain or snow is occurring. The external control unit activates and operates the deicing system as required. A controller is expected to not only detect snow or rain conditions but to also directly control the attached equipment. A DS series unit set as a controller provides a longer delay off time, typically 30-90 minutes or 2-6 hours, allowing the heating system to dry the surface and prevent refreezing.

The M326A-2Z is compatible with the remote “control/monitor” interface,(M326-CDP) where the system can be remotely monitored for activation of the system and/or manually activate or disable the system.
