Monitron Compact, easy to install for new or “standby” installations

Monitron combines the availability and dependability of electricity with the comfort and performance of conventional hydronic heating using baseboard, radiant or cast-iron radiators.

Monitron as a replacement unit: Works with virtually any existing hot water hydronic radiation system. Although rated in kilowatts, it is also clearly identified by BTU output.

Monitron as a standby unit: Particularly suitable for commercial and industrial facilities, or office buildings which can’t risk down-time with their existing heating equipment. If oil or gas is temporarily unavail- able, the owner easily switches the heating system to the electric boiler.

Monitron as a primary heating unit offers:

•The convenience of electricity and the comfort of hydronics.

•The elimination of a chimney.

•Competitive pricing with electric baseboard systems.

•Simple zoning by zone valves.

Monitron by Slant/Fin is the electronic-age boiler designed to save energy for new or existing heating systems.

NORMAL OPERATIONS

When the thermostat calls for heat, the circulator turns on and the first electric heater bank is energized. At preset 30-second intervals, the other heater banks automatically energize. The circulator contin- ues operating until the room thermostat is satisfied. A flow switch supplied by Slant/Fin or others is required. It prevents the elements from being energized unless the circulator is operating. This avoids element burnout.

* All models except EH-8 and EH-10

OPTIONAL MILD-WEATHER OPERATION

Mild-weather energy savings are made possible through the use of circuit breakers on the breaker panel. This permits the owner to manually switch off one or more of the elements. Then, when just a moderate amount of heat is needed, all the elements are not ener- gized, cycling is reduced, and overheating is diminished. This ener- gy-saving feature is standard on Monitron models EH-12-S through EH-40-S.
