5.3 MODES OF OPERATION
KC Series Water Heaters are capable of being
operated in either the Constant Setpoint Mode
or Remote Setpoint Mode. In addition to the
Constant and Remote Setpoint Modes, KC and
Benchmark Series Boilers can also be operated
in the Direct Drive Mode, Boiler Management
System (BMS) Mode, Indoor/Outdoor Reset
Mode or Combination Mode.
The following paragraphs briefly describe the
required connections and menu settings to place
the unit in each of these modes.
5.3.1 Constant Setpoint Mode
The Constant Setpoint mode is used when a
fixed header temperature is desired. Common
uses of this mode of operation include water
source heat pump loops, and indirect heat
exchangers for potable hot water systems or
processes.
There are no external sensors necessary to
operate in this mode. While it is necessary to set
the desired setpoint temperature, it is not
necessary to change any other temperature-
related functions. The unit is factory preset with
settings that work well in most applications.
Prior to changing any temperature-related
parameters, other than the setpoint, it is
suggested that an AERCO representative be
contacted. See Sections 2 and 3 for complete
listings of temperature related menu functions
and factory defaults.
5.3.1.1 Setting The Setpoint
The setpoint temperature of the unit is
adjustable from 40°F to 240°F.. To set the unit
for operation in the Constant Setpoint Mode, the
following menu settings must be made in the
Configuration Menu:
MENU OPTION SETTING
Boiler (or Heater)
Mode Constant Setpoint
Internal Setpt Select desired setpoint
using ▲ and ▼ arrow
keys (40° to 240°F)
Refer to paragraph 2.2 for detailed instructions
on changing menu options.
5.3.2 Remote Setpoint Modes
The unit’s setpoint can be remotely controlled by
an Energy Management System utilizing either a
current or voltage signal level.
