† THERMOSTATS -
HVAC Thermostats may be read and/or controlled by the control and its automation rules engine. This
menu allows each thermostat to be assigned a 12 character description for easy reference in an automation rule. Currently
compatible thermostats include: RCS, Aprilaire, and HAI. Due to the various data protocols, a Lighting/Thermostat/Serial
Interface Expander (ELK-M1XSP) is needed to couple the data bus to HVAC thermostats. Depending on the brand of
thermostat, its wiring interface (RS-232 or RS-485), 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
centers, etc. A message to the keypad could be “Happy Birthday” or “Please Pay Your Bill”, while a message going out a serial
port might be a series of ASCII characters formatted to a certain manufacturers protocol. Special options built into this menu
include: automatic display of temperature readings from Zone Temperature Sensors (ELK-M1ZTS) and from the temperature
sensor built into an LCD Keypad. The sending or receiving of text messages is controlled by the automation rules engine.
NOTE: Text messages share the same memory space as rules. The total number of text messages and rules is limited
by the M1 model that you are installing.
