SETUP MENU
The SETUP menu has 3 submenus: UNIT SETTINGS,
FAN SETTINGS, and TIMERS.
1. UNIT SETTINGS
The UNIT SETTINGS menu consists of 8 submenus:
MODEL, UNIT SIZE, UNIT TYPE, Reversing valve [RE-
VERSE VALVE] settings, Secondary Hot Water Coil [SEC
HW COIL], Auxiliary Relay 1[AUX 1], [FAN] CONSTANT
SPEED or CONSTANT PRESSURE driven operation, and
anti-frost temperature setting [AFST TEMP].
1.1 MODEL: This menu will allow you to select the
model of the unit: ESP or WCSP.
1.2 UNIT SIZE: There are 6 unit sizes options:
2430H/V, 3642H/V, and 4860H/V.
1.3 UNIT TYPE: An ESP model can be configured
as refrigerant heat pump by selecting [HP], or as
cooling only mode available [AC] unit. A WCSP
mode can be configured as a Reverse cycle
chiller [RCC], or as a cooling only [AC] unit or as
a heating only mode [HEAT] unit.
Note: These selections should only be changed by a
qualified installer and should be verified for the
installation.
Note: The unit model, and size will be configured
specific to the purchased unit from the factory.
For ESP units:
For WCSP units:
1.4 REVERSE VALVE: The Reversing Valve
[REVERSE VALVE] can be set to O [energized in
cooling] or B [energized in heating]
1.5 SEC HW COIL: The Secondary Hot Water Coil
menu [SEC HW COIL] allows you to add a
secondary heating water coil as an optional item.
1.6 AUX 1: The Auxiliary 1 Relay [AUX 1] can be
set to close its contacts only during a heating
call, only during a cooling call only or on both
heating and cooling calls.
1.7 Fan Speed: The fan can be run at either a
constant speed or a constant static pressure.
When Constant Speed is selected a different speed %
can be selected for each input. (Y1, Y2, W1, W2, or
G). The fan will run at the set speed % for the active
input. This setting can be from 5% - 100%
When Constant Pressure is selected a different static
pressure setpoint can be selected for each input. (Y1,
Y2, W1, W2 or G). The fan will vary its speed to
maintain the static pressure target of the active input.
See section 2, FAN SETTINGS, for information on
setting the speed % or static pressure setpoints.
1.8 Anti-Frost protection temperature setting:
The Anti-Frost Protection Temperature setting [AFST
TEMP] controls the integrated Anti-frost feature. The
default setting is 34°F, and is adjustable up to 50˚F.
The temperature of the primary coil is constantly
monitored. If the coil temperature drops below the
Anti-Frost Protection Temperature setting the Anti-
frost feature will be enabled, the fan will continue run
at the called for speed, but all HVAC outputs will be
disabled. The feature will be disabled once the
primary coil temperature rises 10°F above this setting.
