Notes:
1. The output mode settings apply only to a 4-pipe system. In a 2-pipe system, output 1 will always operate in the changeover
mode.
2. The floating-mid option is for changeover applications, only, and uses only one of the two outputs.
3. The operation of the triacs based upon the output type is given in Table 12 on page 21 and in Table 14 on page 23.
4. W7754K1001 is equipped with a low-voltage digital output suitable for connection to a solid-state relay employed for low-
voltage PWM control in high-current electric reheat applications; this digital output is activated if output 1 type is set to either
"PWM" or "thermal".
