Figure 8 – Tachometer and Pump Motor Thermostat Connections
To connect the Tachometer Input, connect the wire labeled VDC (typically brown) to the connection
point labeled 1–TACH [+] on connector J-10 CONTROL. Connect the wire labeled TACH (typically
blue) to the connection point labeled 2–TACH [-] on connector J-10 CONTROL. Make these
connections using the 22 AWG wire provided with the Tachometer Sensor (refer to Figure 8).
For additional information relating to the Tachometer Sensor, refer to Section 13 – Repairs: DLC
Replacement.
The Tach input is designed for use with the supplied sensor only. Do not attempt to use any other
device (e.g.: motor based tachometer outputs).
It is permissible to run the pump motor thermostat in the same conduit as the pump motor power.
The signal is conditioned to prevent erroneous operation due to cross-talk.
