Figure 14.9.1. Connection diagram of C35-FC… (D1) and FC-RB (D2)
For applications with 3/1 speed motor and/or with thermal valve actuators which are
controlled by mechanical and solid state relays, use the FC-RB fan coil relay board.
Voltage output (AO1) from the C35-FC device is applied to analog input 1 (AI1) of the FC-RB, and
it controls the 3 or 1 speed fan through digital outputs (DO1, DO2, DO3).
