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 heater is enabled via dry contact at the Enable/Disable connection at 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. See Fig. 35.

NOTE: For Modes 7 and 8, connect to pins 13 and 14 on the low-voltage panel. See page 21. Use these modes for systems using an external signal.

*Maximum 4 times the pipe diameter or 12”, whichever is less.
