FACTORY DEFAULTS
The control comes preset with several factory defaults. These defaults are based on the terminal unit selection (see section
B2). To fine-tune building requirements, these defaults may be changed. If a factory default value for a terminal unit is changed,
the terminal unit number will flash when selected in the ADJUST menu.
To reload the factory defaults listed in section B2, power down the control and wait for 10 seconds. Power up the control while
simultaneously holding the Item and
than flashing.

MIXING DEMAND
A mixing demand is required in order for the 360e to provide heat. A mixing demand
is generated by applying a voltage between 24 and 230 V (ac)across the Mixing
Demand terminals (1 and 2).Once voltage is applied, the Mixing Demand pointer is
displayed in the LCD. If the 360e is not in WWSD, the 360e closes the Sys Pmp con-
tact. The 360e calculates a MIX TARGET supply temperature based on the outdoor air
temperature and settings. If required, the 360e operates the boiler in order to provide
heat to the mixing valve.
SYSTEM PUMP OPERATION (SYS PMP)
The system pump contact (Sys Pmp, terminal 5) closes whenever there is a mixing demand and the 360e is not in WWSD.
The system pump segment is displayed in the LCD. After the mixing demand has been satisfied, the 360e continues to operate
the system pump for 20 seconds. This allows some residual heat to be purged out to the heating system. During WWSD, the
system pump is operated based on the exercise function.
INDOOR SENSOR
An indoor sensor may be used in order to provide indoor temperature feedback. The indoor sensor is connected to the Com
and Indr terminals (16 and 18). In addition, power must be applied to the Mixing Demand terminals (1 and 2) as described in the
MIXING DEMAND section. With the indoor sensor connected, the 360e is able to sense the actual room temperature. Indoor
temperature feedback fine-tunes the supply water temperature in the mixing system to maintain room temperature. To adjust
the room temperature, use the ROOM OCC or ROOM UNOCC setting in the ADJUST menu at the control.
If a multiple zone system is used with an indoor sensor, proper placement of the indoor sensor is essential. The indoor sensor
should be located in an area which best represents the average air temperature of the zones.
CHARACTERIZED HEATING CURVE
When used as a mixing reset control, the 360e varies the supply water temperature based on the outdoor air temperature. The
control takes into account the type of terminal unit that the system is using. Since different types of terminal units transfer heat
to a space using different proportions of radiation, convection and conduction, the supply water temperature must be controlled
differently. Once the control is told what type of terminal unit is used, the control varies the supply water temperature according
to the type of terminal unit. This improves the control of the air temperature in the building.
MIXING TARGET TEMPERATURE (MIX TARGET)
When used as a mixing reset control, the MIX TARGET temperature is calculated from the Characterized Heating Curve set-
tings, outdoor air temperature and optionally, indoor air temperature. When used as a setpoint control, the installer sets the
MIX TARGET temperature. The control displays the temperature that it is currently trying to maintain as the mixing supply
temperature. If the control does not have a mixing demand,"- - -" is displayed as the MIX TARGET.
