• Verify that Hydro Kit PCB DIP Switch Group 2 is set correctly for water tank (domestic hot water) + floor heating installation applications
(this application is the factory default setting). (Refer to the Hydro Kit DIP Switch Settings pages in the Pre-Commissioning section.)
• The domestic hot water tank is for hot water applications and uses the indirect heat exchange method for heating;
freeze like ethylene glycol to its water.
• For sensing air temperature at a specific area, choose a remote temperature sensor or a wired remote controller, depending on the Hydro
Kit PCB DIP Switch Group 3 setting. (Refer to the Hydro Kit PCB DIP Switch Settings pages in the Pre-Commissioning section.)
• When installing a floor heating system, to measure room temperature, use the Hydro Kit controller or a remote temperature sensor (sold
separately).
• See the Indirect Water Storage Tank Sensor Well and Sensor Installation information. To prevent condensation from forming in floor cooling
applications, set minimum / maximum cooling temperatures.
• For three-way valve and / or two-way valve control, see the Wiring section.

• When selecting a water tank,
ALWAYS use an INDIRECT tank
where the Hydro Kit water circuit
is isolated from the domestic
water system. Failure to follow
instructions will result in product
malfunction.
• The heating operation mode of
the water tank (domestic hot
water) is not a mode selection
using the remote controller. The
heating operation mode switches
Floor Heating
the three-way valve operation to
the water tank operation based
on the water tank temperature.
• It is impossible to operate water
tank (domestic hot water) during
cooling mode.
