The heater is operated as in Mode 2. However, the target temperature is based on outdoor reset. See Fig 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 0-10VDC 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.
