SENSOR LEAD CONNECTIONS
Connect male/female plugs of all sensors and/or components. Each of the male and female connectors is
labeled to ensure the proper connections are made. Refer to appendix B for a cross reference list of labels
and connections. If this is an Acorn BASyC upgrade, sensors and/or actuator(s) will first need to be installed
into the mixing valve assembly appropriate installation methods. Refer to sketch in cabinet to help determine
where the sensors should be installed.
Important:
Observe coding to insure proper mating –
ex: male connector #1 with female connector #1.
The standard, highly accurate, stainless steel
encased outlet temperature probe is preinstalled.
The exact number of temperature probes
provided varies, depending on the configuration
of your single or multi-valve mixing assembly.
NETWORK COMMUNICATIONS
Acorn BASyC™ includes several different types of network interfaces to ensure both versatility and
adaptability. Each controller includes two Ethernet ports (primary & secondary), an RS-232 port and an
RS-485 port as shown below. Connections to the primary and secondary Ethernet ports are via standard
category 5e/6 wiring with male RJ45 connectors. The RS-232 port can be connected using a DB-9 male
plug while the RS-485 port utilizes a 3-position connector jack. In all cases, it is recommended to refer to
the communication protocols documentation in order to configure and wire these properly. It is beyond the
scope of this document describe all the considerations for this.
Available communication options:
- Ethernet TCP/IP
- BACnet TCP/IP
- BACnet MSTP
- Lonworks
- Modbus RTU/ASCII
- Modbus TCP/IP
- oBIX
LAN adapters (primary shown on right) and serial ports that can
be configured to RS-232 or RS-485.
