Relay, Counter Timer Control Mode
ONLY AVAILABLE IF HVAC MODES ARE DISABLED IN CONFIG MENU – GLOBAL SETTINGS
The Counter Timer algorithm activates the relay for a programmable amount of time, triggered by the accumula-
tion of a programmable number of contact closures from a Digital Counter type input.
Output Details
The details for this type of output include the relay on/off state, HOA mode or Interlock status, time on, remain
-
ing on-time, accumulator total, total relay activation time, alarms related to this output, relay type and the current
control mode setting.
Settings
Touch the Settings icon to view or change the settings related to the relay.
Feed Duration
Enter the amount of time for the relay to activate for once the accumulated setpoint
number of contact closures has been reached.
Accumulated Setpoint
Enter the number of contact closures required to trigger the relay activation.
Input
Select the input to be used to control this output.

Relay, Dual Switch Control Mode
Dual Switch mode is typically used to fill or empty a tank, using a level switch contact closure to activate the relay
when the liquid level is at one extreme and deactivate the relay at the other extreme. It is more versatile than that;
the on and off triggers may be any digital input or relay output state.
Note that the Dual Switch control relay will only respond to trigger relay state changes that occur when that relay
is in Auto mode, not if the trigger is activated manually using Hand or Off modes.
Output Details
The details for this type of output include the relay on/off state, HOA mode Interlock or delay status, current cycle
on time, the total accumulated on-time since the last reset, alarms related to this output, relay type, and the current
control mode setting.
Settings
Touch the Settings icon to view or change the settings related to the relay.
On Switch
Select the digital input or output that will trigger the relay to activate.
Activate On
Select the state of the digital input or output that will trigger the relay to activate.

Enter the delay time for relay activation in hours:minutes:seconds. Set the time to
00:00:00 to immediately activate the relay.
Off Switch
Select the digital input or output that will trigger the relay to de-activate.
Activate Off
Select the state of the digital input or output that will trigger the relay to deactivate.
Off Delay Time
Enter the delay time for relay deactivation in hours:minutes:seconds. Set the time to
00:00:00 to immediately deactivate the relay.
