INSTALLATION MANUAL AND OPERATING INSTRUCTIONS ARM “TANKLESS COIL” APPLICATION REMOVE factory installed jumper between ZC and ZR. ARM “TANKLESS COIL” APPLICATION Tankless coil requires a boiler aquastat. Each zone thermostat will signal the ARM to start its zone circulator and send a call for heat to the boiler aquastat. - Page 12 When using ZC-ZR careful attention must be paid to keeping the polarity of the wiring consistent between the Argo control and the boiler aquastat. Failure to do so could result in a secondary source of power activating the boiler under certain circumstances which could result in serious injury or death.
