Hot Water Mode

The Trilogy unit provides significant savings when used to heat
domestic water. Domestic hot water is available on demand
and is available year round utilizing heat from the earth or
reclaiming wasted heat from the space cooling mode. Hot water
capacities are provided in the appropriate Trilogy performance
data. The Trilogy 45 unit combined with iGate
®
capable of storing Water up to 135°F (57°C) degrees. Domestic
hot water is provided by a double wall vented brazed plate heat
exchanger suitable for potable water use.
The Trilogy Q - Mode geothermal unit has two dedicated hot
water modes, 1) heating domestic hot water with heat from
the geothermal source and 2) heating domestic hot water
with heat from the space cooling mode. The Trilogy unit is
designed to be used with the iGate Connect thermostat and
the iGate Smart Tank.

Description
Configures the sensitivity of the thermostat to the space temperature. A
lower setting will cause the unit to respond more rapidly to changes in space
temperature. A higher setting will cause the unit to respond more slowly to
changes in space temperature.
Determines the point at which the space cooling demand outpaces the ability of
the potable water heating mode to accept the heat of rejection from the cooling
mode when both are active at the same time. At this setting and above the heat
of rejection from the cooling mode will be sent to the source (ground loop).
Potable water heating normally takes priority over space heating. This setting
determines the point at which the space heating demand will take priority over
the potable water heating demand.
Configures the amount of space temperature droop allowed from the heating
setpoint at maximum unit capacity before allowing auxiliary heat for space
heating.
This setting establishes the maximum acceptable space temperature rise
during the cooling mode while the heat from the space is being rejected into
the potable hot water. If the space temperature rises more than this amount,
the potable water heating mode will be terminated and the cooling mode will
reject the heat from the space to the source (ground loop).
This setting establishes the maximum acceptable space temperature drop
during the potable hot water mode before the unit switches to the space
heating mode. If the space temperature drops more than this amount, the
potable water heating mode will be terminated and the space heating mode will
be activated.
Description
When Hot Water Efficiency is enabled (ON) the AWS backup electric elements
will operate when the connected heat pump is locked out or when the heat
pump cannot keep up with the household hot water demand. When Hot Water
Efficiency is disabled (OFF) the iGate Smart Tank electric elements will engage
sooner when the connected heat pump is locked out or when the heat pump
cannot keep up with the household hot water demand.
Determines the heat source for your hot water.
Establishes the set point for your hot water.
Configures the amount of droop allowed from the potable hot water setpoint
before activating water heating.
Description
Sets the potable water flow rate for the water heating mode. The variable
speed potable water pump will adjust the potable water flow to maintain the
selected temperature difference between the entering and leaving potable
water during the water heating mode.

Configuring the Hot Water Mode
There are multiple configuration settings available for the hot
water mode on the Trilogy unit. Utilize the myUplink Pro app or
Service tool to change any of the options shown below:
⚠
WARNING!
WARNING! Using a hot water setpoint of 125°F or above will
result in water temperatures sufficient to cause severe physical
injury in the form of scalding or burns. A hot water setpoint
temperature above 125°F must only be used on systems that
employ an approved anti-scald valve (part number AVAS4) at
the hot water storage tank with such valve properly set to control
water temperatures distributed to all hot water outlets at a
temperature level that prevents scalding or burns.
