MODE 5 and 6 – External Target Temperature

Applications

MODE 5 – EXTERNAL TARGET TEMPERATURE INPUT & DHW OPERATION-PARALLEL PIPING
The control receives a heat demand provided via an external analog input signal from an EMS, BMS or tekmar tN4 sys-
tem control. The external analog input signal is interpreted as a setpoint target temperature. The control turns on the boil-
er pump and operates the boiler to maintain the setpoint boiler target temperature at the boiler outlet sensor. The control
receives a DHW Demand from a DHW aquastat. The control turns on the DHW pump, and operates the boiler to maintain
the DHW setpoint boiler target temperature at the boiler outlet sensor whenever a DHW demand is present.
MODE 6 – EXTERNAL TARGET TEMPERATURE INPUT & DHW OPERATION-PRIMARY / SECONDARY
The control receives a heat demand provided via an external analog input signal from an EMS, BMS, or tekmar tN4
system control. The external analog input signal is interpreted as a setpoint target temperature. The control turns on the boil-
er pump and operates the boiler to maintain the setpoint boiler target temperature at the boiler supply sensor. The
control receives a DHW Demand from a DHW aquastat. The control turns on the DHW pump, boiler pump, and operates the
boiler to maintain the DHW setpoint boiler target temperature at the supply sensor whenever a DHW demand is present.
