INTRODUCTION
This application is for a pressure dependant VVT zoning system using one SE8600 Series Room Controller, for the heat pump or
rooftop, multiple SE8300 Series Room Controllers (2-20) for the zones and one Gateway Multi-purpose Manager (MPM-GW).
The SE8600 can be set for 1C/1H, 2C/2H, modulating heat, economizer and CO
damper or a VFD. This can be accomplished directly from the interface of the SE8600 Room Controller. It is also used to set the
occupancy schedule, configurable on the Room Controllers HMI.
The SE8300 Series Room Controller can control a 0-10 Vdc modulating damper, a 0-10 Vdc duct heater and a baseboard. Added
parameters include the following:
• damper Min_Pos
• damper Heat_Pos
• PI_Heat_Weight
• PI_Cool_Weight
In order to facilitate system balancing, it is possible to force all zone dampers to the fully open position for a specific time duration
(between 1 and 240 minutes).
A built-in comfort feature will override the damper minimum position if the Room_Temperature deviates too far from setpoint. All
configurations are done on the Room Controller.
The MPM-GW is used to calculate the highest zone PI_Heat & PI_Cool demands, transfer the Occupancy, System_Mode and to
coordinate all ZigBee communication. The database includes one SE8600 Room Controller and 20 SE8300 Room Controllers
according to the following:
• Integrator sets up the ZigBee network and then discovers the Room Controllers
• any unused Room Controllers should not be deleted
• other MPM-GW functionality such as trending, scheduling, and dashboards can be used
, and will control the static pressure using a bypass

SE8600 SEQUENCE OF OPERATION
The SE8600 will control the RTU/HPU based on the “Highest Heating or Cooling demand” and the “Global Combined Cool & Heat
demand” from the SE8300 Zone Room Controllers. If Cool and Heat demands are equal, the cooling demand takes precedence the
heating demand. There is a 2-minute delay (adjustable) between Cool/Heat and Heat/Cool System_Mode change. The output for Static
Pressure Control is direct acting (0-10 Vdc = 0-100%), which is ideal for VFD applications. For a bypass damper it is important to have
the damper “open-to-bypass” at 0 Vdc and “closed” at 10 Vdc.
SE8300 SEQUENCE OF OPERATION
The SE8300 controls a modulating (0-10 Vdc) damper actuator, according to the SE8600 System_Mode. The Room Controller does not
require a changeover temperature sensor, however it does controls a modulating (0-10Vdc) duct heater and an On/Off baseboard.
When the system is Unoccupied, pressing the Override key of a Zone Room Controller will only Override the Zone. To Override the
RTU/HPU, the Override key of the SE8600 must be pressed.
Information transferred from the SE8600 RTU/HPU controller to the SE8300 Zone Room Controllers is as follows:
• Occupied/Unoccupied command
• Heat or Cool system mode
• Damper Override, 100% open, for balancing purpose
SETUP INSTRUCTIONS
1. Using Uploader Tool, upload two Lua scripts to each SE8300 Room Controller and each SE8600 Room Controller.
NOTE: it is essential to upload the Lua scripts in the correct sequence. Upload file 1 of 2 first and 2 of 2 last.
