Wiring All Ready-To-Run (Rtr) Models - Amtrol BoilerMate RTR Installation & Operation Manual

10. WIRING ALL READY-TO-RUN (RTR) MODELS

Ready-To-Run models include a circulator with built-in priority zoning relay. The aquastat is pre-wired and controls the
circulator. Line voltage must be supplied and a signal wire must be run to fire the boiler.
To wire RTR models, select the appropriate diagram from the following pages. If a suitable diagram is not available for your
application, please contact AMTROL Tech Support at (401)535-1216. Always disconnect power before wiring the unit. Ensure
that the proper conduit and connections are used per your local code. In lieu of local code, the National Electric Code should
be followed.
