Periodic Pulse Reduced
Cavitation - can only disable if
boiling set below 98°C (209°F)
(Boiling models) Two electric
pulses are sent every 5 minutes to
the pump. This prevents the build
up of air bubbles inside the pump
and ensures an even flow of hot
water at the faucet.
Power Pulsing - can only disable
if boiling set below 98.5°C (210°F)
(Boiling models) This is a
default set point control feature which ensures the hot water is
maintained as close as possible to the set point. This is achieved
by applying a closer tolerance to the set point temperature range.
Fan speed adjustment
(Residential and small commercial models) Adjust the fan speed
to reduce noise. If the Command Center is operating near 35°C
(95°F), then the fan speed must be set to 100%. The fan speed
may be adjusted for quieter operation only if the operating
temperatures are considerably lower than 35°C (95°F).

Advanced Settings (more)
Pre-pulse Reduced Cavitation
Mode (Boiling models)
Enabled (default): An electric
pulse is sent to the pump before
every dispense of boiling water to
prevent build up of air bubbles and
ensure an even flow of hot water.
Wave Faucet Sensor Demister Mode
Enabled (default): activates the Wave Faucet internal heater to
prevent its sensors from being affected by condensation from steam.
Disabled: conserves a small amount of power.
Wave Faucet Lock Mode
Disabled (default): Chilled or sparkling water can be dispensed by
activating the corresponding sensor.
Enabled: in addition to the chilled or sparkling sensor, the
rear sensor must also be activated in order to dispense chilled
or sparkling water. This is useful to prevent false activation if
a highly reflective surface is present (such as high-visibility
reflective tape). The Bottle Fill function will be disabled.

Zip HydroTaps are designed to operate within 1° to 2° of set point for
boiling water and 6 - 10°C (43 - 50°F) for chilled water. Boiling water
units are self-calibrating to 98°C (208°F) (recommended setting).
Adjustments to this setting are not recommended however, under
certain circumstances adjustments may be made between 68 - 100°C
(154 - 212°F). NOTE: A 6% energy saving in standby power can be
achieved with a 98°C (208°F) setting compared to 100°C (212°F).
Furthermore, the 100ºC (212°F) setting is not recommended as the
delivery rate of water will be affected.
