Application: ASW sensors are wall-mounted temperature sensors for use with the MPC controller on Water-to-Air units. The ASW is available in 3 different models to allow for application flexibility. Features such as room temperature sensing, digital LCD readout, set point adjustment, override push button, heat pump reset, lockout recognition, fault type, LED indicator, cosmetics and occupancy status can be supplied by the different types of ASW wall sensors. The ASW wall mounted sensors are low profile, which provides a distinguished look for building architects and engineers.
Wiring: PREREQUISITE: The RNet cable is wired to the controller. The shield wire and the ground wire should be inserted into the controller’s GND terminal, insert the other 4 wires into the RNet Sensor’s screw terminal connector. If wiring 2 cables, insert like colored wires into each terminal. It is recommended that you use the following RNet wiring scheme: Connect this wire… To this terminal… Red +12V, Black RNet-, White RNet+, and Green Gnd.
