*Maximum4 times the pipe diameter or 12”, whichever is less.
Mode 6 – Primary piping is prohibited.
Mode 7 – Designed for an external input signal with
primary/secondary piping. The external input signal
can be provided from a BMS, an EMS or a sequenc-
ing control. The external input signal changes the
boiler target according to a linear scale. The control
operates the boiler burner to maintain the boiler target
at the remote system sensor. See Fig. 38.
Mode 8 – This mode is for remote firing control of the
heater via an external sequencer such as the Raypak
TempTracker MOD+. The Boil Max setting is the
heater shutdown temperature (max temperature). The
heateris enable d via dry contact at the Enable/Disable
connectionat the low voltage terminal strip, and the fir-
ing rate is controlled by a 0-10 VDC signal from the
external sequencer. A control signal of ≥0.5 VDC
equates to minimum fire, and a signal of 10 VDC
equates to 100% firing rate.
