WARNING!
Connecting household line voltage to any terminal other than
those indicated on the terminal connection detail below will
cause damage to the PB-1525 wood pellet burner system and
voids the warranty.
WARNING!
The PB-1525 must be connected to a proper ground connection
as labeled.
Connecting the Controller to the Thermostat
1.
The PB-1525 connects to a standard, normally open dry contact
thermostat. System firing will be controlled by the demand called
for by the thermostat.
2.
The thermostat connects to the PB-1525 as indicated in the terminal
connection detail above.
WARNING!
Connecting any low voltage to the Thermostat terminals of the
PB-1525 wood pellet burner system will result in improper and
potentially dangerous system operation and system damage.
The Thermostat connections are for Normally Open (N.O.) Dry
Contacts only. Applying AC or DC voltage to the thermostat
inputs to the system voids the warranty.
3.
An optional universal voltage input relay is available for installations
where the existing control circuit provides direct 120V AC or 24V
AC/DC to the burner for operation. IF required, this relay is installed
within an exterior control box. Connect the control voltage as
indicated on the relay and connect the Normally Open (N.O.) relay
outputs to the thermostat inputs of the PB-1525 as indicated.
The Functional Devices RIBU1C is an acceptable input relay for use
with the Pellergy PB-1525 wood pellet burner system. The schematic
detail of the RIB is shown below in Figure 2.8. As an example
connection, the burner powered outputs of an aquastat controller
