Flow switches
Do not modify or disconnect the internal connections. The flow switches protect your
E

from thermal damage if cooling water to the heat sink or to the coil is
inadequate.
To add your optional normally-open flow switch, remove jumper at CTB1:6-7, connect
your flow switch wires. Inadequate flow to your flow switch will then result in
Fault.
Status signals (CTB1:8-13)
Case: You connect your 24Vdc source and monitoring equipment (ex., current-limited
LEDs) to remotely track the status of the E
