LED MODE Function
ON Temperatures are displayed in degrees Fahrenheit.
ON Temperatures are displayed in degrees Celsius.
Flashing Output 1 time delay. Output 1 will not energize until AC1 time delay expires OR i3F=Edi and
the remote enable/disable is in standby (disabled).
ON Output 1 relay is on. Spade contacts 4 & 5 are closed.
Usually this is the primary CALL FOR HEAT.
Flashing Output 2 time delay. Output 2 will not energize until AC2 time delay expires. (On 2-stage
units only)
Or oS2 is set to AL. (Output 2 is an alarm indicator and it is off.)
ON Output 2 relay is on or the AL2 alarm output is enabled. Spade contacts 6 & 7 are closed.
Flashing Output 3 time delay. Output 3 will not energize until AC3 time delay expires.
ON Output 3 relay is on. Spade contacts 8 & 9 are closed.
ON Modulation output signal is in manual control mode. Parameter PS4 should be set to nu for
automatic operation.
Or If dS1 or dS2 is set to display the modulation output value ANI.
Flashing Modulation is forced to value in i1S by digital input 1.
ON Modulation output signal is automatically controlled by temperature probe 1.
Flashing Modulation output time delay is activated. Modulation output will remain at 4mA until the AC4
time delay expires.
Or Modulation will remain in low fire until probe 2 is below TH4 by the amount of HY4.
Ext
ON The outside temperature is displayed (top or bottom display). See dS1 & dS2.
FLASHING Digital input 2 (alarm) is activated.
FLASHING Digital input 3 (alarm) is activated.
FLASHING
When both
and are flashing other safety interlocks such as low water cut-off or high
temperature limit may be in failure.
ON Lower LED display is displaying time clock.
Pr1
ON While in the Pr2 menu, signals that current the parameter is accessible in the Pr1 menu.
FLASHING ALARM signal (any alarm condition LA, HA, P1, P2, P3, AL2, AL3, Nn1, Nn2, Nn3).
FLASHING Programmed working hours limit is exceeded See oP1, oP2, oP3 & ou1, ou2, ou3.
ON Working hours are displayed in the lower LED display.
ES ON The Energy saving function is running This is a LED dot under the ES label top left.
PoF Pops Up Displayed when trying make a change, the Keypad is locked. See section 4.5.
