C. Relay Action, Relay Setpoint, Hysteresis Mode & Hysteresis Value

If the relay control type is set to HI and the hysteresis mode is

CENTER

, the relay will turn

at [(RELAY SETPOINT) + (0.5 * hysteresis value)], and will turn

OFF

at [(RELAY

SETPOINT) - (0.5 * hysteresis value)].

If the relay control type is set to HI and the hysteresis mode is

EDGE

, the relay will turn

at (RELAY SETPOINT), and will turn OFF at [(RELAY SETPOINT - (hysteresis value)].

If the relay control type is set to LO and the hysteresis mode is

CENTER

, the relay will turn

OFF

at [(RELAY SETPOINT) + (0.5 * hysteresis value)], and will turn

at [(RELAY

SETPOINT) - (0.5 * hysteresis value)].

If the relay type is set to LO and the hysteresis mode is

EDGE

, the relay will turn

OFF

[(RELAY SETPOINT) + (hysteresis value)], and will turn

at (RELAY SETPOINT).
