CUSTOM SETTINGS -
These are 20 memory locations which may be assigned a 12 character description, a function type
(one of 3), and a starting value. An authorized user can then access the custom settings from keypad user menu 7-
Automation Custom Settings, and modify the value whether it be a numeric value, a timer (seconds), or a time-of-day.
Incorporating custom settings in rules provides the user the ability to modify how the rule will operate. For instance, the user
can modify the time or duration for the lawn sprinklers which have been programmed to turn on automatically. The function
types include: A 5 digit raw number with a range of 00000 to 65,535, a 5 digit timer (seconds) with a range of 00000 to 65,535
seconds, or a Time (time of day) which is formatted as 00:00 with a range of 00:00 to 23:59.
COUNTERS -
These memory locations (often called flags) can be set, incremented, decremented, or compared by an
automation rule to track an event or keep up with how many times an event has occurred. There are a total of 64 counters.
Each can be programmed with a 12 character description, making it easy to reference in an automation rule.
THERMOSTATS -
HVAC Thermostats may be read and/or controlled by the automation rules engine. This menu allows each
thermostat to be assigned a 12 character description for easy reference in an automation rule. The compatible thermostats
are: RCS, Aprilaire, and HAI. Due to the various data protocols, a Lighting/Thermostat/Serial Interface Expander (ELK-M1XSP)
is needed to couple the M1 data bus to HVAC thermostats. Depending on the brand of thermostat, its wiring interface (RS-
232 or RS-485), and the model of control that you are installing, up to 16 HVAC thermostats can be controlled. Many
communicating thermostats operate stand-alone when they are not being remotely commanded by an automation controller.
TEXTS -
This section allows custom text messages to be constructed and formatted. These messages can be transmitted to
an LCD keypad or out one of the RS232 serial ports to a PC or some other type of equipment. I.E. Touchscreen, Lighting
