The W7754K features an extra socket (2-pin connector located to the left of the terminal blocks) containing an output suitable for attachment to a solid-state relay
(use only Carlo Gavazzi RS1A23D25-P64; max. voltage = 12 VDC; max. current = 12 mA at 10 VDC) for low-voltage PWM control in high-current electrical reheat
applications. To enable it, term. 19 and 20 must be configured (via LNS plug-in) for “Heat” -> “PWM”.
(2)
For AO1 (terminal 12) to be used to control a proportional valve, OUT1 (term. 19 and 20) must be configured (via LNS plug-in) for “PWM”, and the fan must not
be configured for “variable speed fan”.
(3)
If all three relays (term. 16, 17, and 18) are switched OFF, the 3-speed fan will likewise be switched OFF. Switching voltage = 24...230 VAC; switching current =
0.05...3 A (max. 3 A for all three relays together).
(4)
Switching voltage = 230 VAC (W7754K,P,R,S,V) or 24 VAC (W7754Q,T), max. switching current = 0.5 A; max. peak (10 sec) current = 1 A
(5)
For output for low-voltage PWM control of a solid-state relay (W7754K, only) to be used, these terminals must be configured (via LNS plug-in) for “Heat” ->
“PWM”.
(6)
In order for AO1 (terminal 12) to be used to control a 6-way ball valve from Belimo, OUT1 must be configured for "Not USED," OUT2 (term. 21 and 22) must be
configured (via LNS plug-in) for "Changeover Mode" type "Floating Mid," and the fan must not use the analog output (no fan or 1…3-speed fan).
(7)
Total current draw of terminals 19 through 24 and 27 through 28 must not exceed 450 mA.
