G. External limits –
To cause MANUAL reset: Terminal Block P13 #1 & #2
SlimFit control will require manual reset after circuit is interrupted
1. Remove factory-installed jumper and connect isolated contacts of external limits
across P13 pins 1 and 2 to cause the control to enter manual reset lockout if
the limit circuit opens. The limit must close and the control must be manually
reset using the procedure given in this manual. See drawing at right and wiring
diagram (Figure 52, page 48).
The control will lockout when a limit in its manual reset circuit opens
(P13 pins 1 & 2). The control activates its alarm terminals and shuts
the boiler off. An operator (user or technician) must manually reset the
control to resume heating. Cycling power on and off will NOT reset
the control.
To cause AUTOMATIC reset: Terminal Block P13 #3 & #4
SlimFit control will reset automatically after circuit is interrupted
1. Remove factory-installed jumper and connect isolated contacts of external
limits across P13 pins 3 and 4 to cause the control to shut down the burner
on limit opening, then automatically restart 150 seconds after the limit closes.
2. See drawing at right and wiring diagram (Figure 52, page 48).
H. Alarm contacts –
Terminal Block P16 #4 & #5
1. The control's alarm dry contact (P16, terminals 4 and 5) closes when the
boiler enters manual lockout only.
2. Connect these terminals for remote alarm notification.
3. Contact electrical ratings: 24 VAC or less; 0.5 amp or less.
