MODEL VOLTAGE DESCRIPTION/OPERATION
727 120 VAC LOW LEVEL CONTROL Maintains level between probes. Energizes pump to refill
tank when liquid level falls below bottom probe. De-energizes pump when liquid
level reaches upper probe. Includes (1) EL1214-SV and (1) EL1214-RSV probes.
787 120 VAC HIGH LEVEL CONTROL Maintains level between probes. Energizes pump to
remove liquid from tank when the level reaches the upper probe. De-energizes
pump when liquid level falls below bottom probe. Includes (1) EL1214-SV and
(1) EL1214-RSV probes.

Temperature Control
MODEL VOLTAGE DESCRIPTION/OPERATION
2000 24 VAC Controls water temperature in indirect water heaters. The control is designed to
closely monitor the rate of tank temperature changes and controls the heating
source to minimize fluctuations in tank temperature, while optimizing fuel efficiency.
