Zoning Heaters and Configuring 'Master/Slave' Heaters

The MP Series is designed to allow for several heaters within the same zone to simultaneously modulate
in synchronization when connected to a single control device. This configuration requires one 'Master'
heater that is connected directly to the heat control device, and the remaining 'Slave' heaters are to be
wired to the 'Master' heater. The 'Slave' heaters will modulate based on the control signal from the
'Master' heater. During the operation of the system, all the 'Slave' heaters will modulate at the same
percentage rate of the full input as the 'Master' heater.
When wiring multiple heaters together for zoning, the heaters must be wired in series with a 'Master'
heater utilizing a shielded thermostat wire. Connect the heaters via the appropriate wiring diagram. See
Pages 9-12 for more information.
Building Management Systems and Other Remote Analog Signals
A Building Management System or a Remote Analog Signal may be used as a controlled device for the
MP Series. This allows the heater(s) to be controlled directly by the output of the Building Management
System directly dictates the heaters firing rate. The analog signal can be either 0-10VDC or 4-20mA.
A Premium User Interface (P/N: PUI) MUST be used in order to connect the Building Management
System to the heater.
