Network Controllers & Schedulers

The XCI family of Network Controller & Schedulers is the heart of XCI's HVAC control networks.  There are several different network adapters to satisfy the requirements of any installation.  The entire Serial-Stat Network Controller family enables simple integration with any control system or personal computer. The controllers accept simple ASCII commands using a published open protocol and replies with readable text answers.  The entire family of controllers has built-in intelligence to correct conflicting and illegal thermostat settings to prevent damage to equipment from programming errors.

The XC-SSA2/CLK network controller is the workhorse of XCI's commercial grade controllers. It is an expandable network controller which allows control of up to several 1000's of thermostats,  in increments of 32 thermostats. The controllers include a real-time clock/calendar which allows simple, yet robust environment control. The real-time clock/calendar is a significant importance to most of our customers. It allows the XCI system to run in a 'stand-alone' mode, where no other controller, PC or automation system is required for scheduling setpoints and modes of operation. When used in combination with the XCI Command Center software, simply point and click to create your schedules, then click to download them into the XCI controller, and you're done! The thermostat schedules will run automatically at the time(s) designated. There are also two smaller controllers, the XC-SSA32/CLK and the XC-SSA16/CLK which are 32 and 16 thermostat non-expandable controller. More details are below!


XC-SSA2/CLK Expandable Network Controller
(for systems with up to 32 Serial-Stat Thermostats and at least 1 XC-REL relay module)

This is the most popular version of XCI's network adapters, and is the big brother of the entire line. This controller (like the others in the line) has a complete real-time clock and calendar, allowing the XCI network to become self-sustaining.  Using the XCI Command Center Software, an entire set of schedules can be created within a point-n-click Windows environment and then downloaded into the controller.  Once this is done, the PC (or Modem or LAN) can be disconnected and the controller will run the schedules you entered.  The device can handle a power outage of 7 days without you having to worry about resetting the clock.  There is room for over 1,000 different schedules, allowing you to create up to 4 difference schedules, 7 days a week, for up to 32 Serial-Stats connected to it, and stll having 104 global schedules left over!  It also allows for connection of XCI's powerful communicating relay package, the XC-REL. The XC-SSA2/CLK makes commercial HVAC control jobs easier than they've ever been before!

XC-SSA32/CLK Non-Expandable Network Controller
(for systems with 32 or less Serial-Stat Thermostats)

This new entry is one of 'offspring' of the original network controller. The XC-SSA32/CLK has all the power and flexibility needed for many projects. This controller is great for systems that have 32 or fewer Serial-Stat thermostats and have no need for the XC-REL communicating relay module. The unit has a complete real-time clock and calendar, allowing the XCI network to become self-sustaining.  Using the XCI Command Center Software, an entire set of schedules can be created within a point-n-click Windows environment and then downloaded into the controller.  Once this is done, the PC (or Modem or LAN) can be disconnected and the controller will run the schedules you entered.  The device can handle a power outage of 7 days without you having to worry about resetting the clock.  There is room for hundreds of different schedules, allowing complete flexibility for your needs!  The XC-SSA32/CLK makes medium-sized HVAC control jobs easier than they've ever been before!
