SySTEM pRE-REqUISITES

These instructions assume that you have already installed the thermostat(s) and wired them to the Distribution Panel according to the Model
8800 System Installation Instructions (Document 10009416) .
If your thermostats are configured as non-programmable, all schedules are stored in the System Controller and setpoints are written out to
the thermostats at the beginning of each schedule event . If the thermostats are configured as programmable, the schedules are stored in the
thermostats . This is advantageous because if communication to the System Controller is disrupted, the thermostats will continue to run the
programmed schedule .
In programmable mode, Progressive Recovery can be enabled at the thermostat . The Progressive Recovery feature allows the thermostat to
activate the heating and cooling equipment pRIOR to a scheduled event in order to reach the desired temperature at the start of that scheduled
event . Example: If the WAKE time is 6 am, and the temperature is 70°, the heat will come on before 6 am, so the temperature is 70° by the
time you wake at 6 am .
IMpORTANT NOTE: Set the thermostat ID numbers to consecutive numbers beginning at 1 .

INSTALLATION STEpS

To install the System Controller you will need to complete the following steps, which are described in the following sections:
1 . Mount the System Controller in a suitable location .
2 . Connect the System Controller to a network or computer .
3 . Connect the System Controller to a Distribution Panel .
4 . Connect power to the System Controller using the included power supply .

STEp 1: MOUNT THE SySTEM CONTROLLER

The System Controller should be mounted to a wall at a location that:
• P rovides access to a power outlet.
• P rovides access to an Ethernet network connection if you plan to access the System
Controller over a network .
• P rovides access to wire the RS-485 communications to the distribution panel.
The System Controller should be mounted in a dry location that maintains normal temperatures
between 40°F and 100°F .
The System Controller does not need to be accessed in normal operation, but should be
accessible for servicing .

STEp 2: pROVIDE pOWER TO THE SySTEM CONTROLLER

The System Controller comes with a power adapter that plugs into a normal 120VAC outlet .
Simply plug the power adapter into an electrical outlet and connect the power plug to
the 5 position connector on the 8826 . It is highly recommended to use a surge protected
uninterruptible Power Supply to power the 8826 .
Illumination of the Power LED on the System Controller indicates power has been established .
