Compact, easy to install for new or “standby” installations
Monitron Deluxe EH-M2/M3 combine the availability and dependability of electricity
with the comfort and performance of conventional hydronic heating using
baseboard, radiant or cast-iron radiators.
Monitron Deluxe Series 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 Deluxe Series 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 tem-
porarily unavailable, the owner easily switches the heating system to
the electric boiler.
• One piece cast-iron heat exchanger.
• Built in air eliminator.
• Internal baffles improve heat transfer.
• Slant/Fin electronic Multi-stage control
The Slant/Fin boiler temperature control is an efficient
boiler operator with digital LED display with backlight,
a boiler pump output and an alarm.
Features:
• Set point operation
• Outdoor reset with DHW priority
• External control through BMS signal
• And much more
Energy saving electronic control
NORMAL OPERATIONS
When the thermostat calls for heat, the circulator turns on and the
first electric heater bank is energized. The circulator continues oper-
ating 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.
OPTIONAL MILD-WEATHER OPERATION
Mild-weather energy savings are made possible through the use of
a warm weather shut-down feature of the control. This energy-
saving feature is standard on Monitron II models EH-24M2 through
EH-40M2 and Minitron III models EH-8M3 through EH-20M3.
Standard equipment
• Multi-stage electronic control
• Pressure and temperature gauge
• Safety relief valve (unmounted)
• Circulator relay and heater power relays
• Circuit breaker (one or two heaters per breaker)
• Drain cock,
3
⁄4 " (packed separately)
• Built-in air separator
• Cast-iron ASME approved heat exchanger
• Terminal blocks for circulator, thermostat, flow switch,
temperature sensors and remote signal input.
• Complete jacketing
• U.L. listed, ASME authorized
• Flow switch. Not included with, but necessary on all models
• Circuit breaker for circulator and control circuit.
Monitron Deluxe Series as a primary heating unit offers:
• The convenience of electricity and the comfort of hydronics.
• No chimney required.
• Competitive pricing with electric baseboard systems.
• Simple zoning by zone valves.
Monitron II/Minitron III by Slant/Fin are the electronic-age boilers
designed to save energy for new or existing heating systems.
