For example, if in the hot water mode, it will modify the hot water tank temperature setting. If in cooling condition mode, it will modify the setting of the returning inlet temperature to the heat pump.
  • Page 27 Note: The room control strategy for heating and cooling, is not controlled by the heat pump. That is done by the thermostat of the air handler or radiant heating zone for example. The heat pump attempts to maintain a buffer tank temperature that is sufficient for the air handler to do the job of heating or cooling that space.

  • Page 37: Intelligent Defrost

    Intelligent Defrost By default, the arctic heat pump is designed to defrost itself as needed. The algorithm is factory supplied based on optimized performance parameters for cold climate. These are based on coil temperature differentials and compressor time run. When unit enters defrost it will go through various stages including a reverse to cooling removing some heat from the buffer tank.

    b. Unit is in cooling or defrost mode OR c. “Emergency” or “AC Remote On” switch is (activated) To connect the backup heater function (terminals) to a remote heating element you will need to use a 240 VAC contactor, as the system is not designed to provide power directly to a heating system due to the amperage restrictions.
  • Page 39 Connect E1 to E1 and E2 to E2 on heat pump and Eco ULTRA Aux heat source dry contact on Eco ULTRA E1/E2 Now when the Arctic Heat Pump calls for supplemental back up heat, the dry contact behind terminal E1/E2 will close, signaling to the boiler to begin contributing energy via its electric heating element.
  • Page 40: Multiple Heat Pumps

    Multiple Heat Pumps Larger power requirements can be accommodated adding multiple heat pumps in parallel. One heat pump becomes the master and the other are the slaves. When adding multiple units pipe sizing should be increased at the common home run pipe to accommodate the added flow of more than one pump. Example if there are three units with 1”...
  • Page 42 Flow Valves- It is recommended when running units in parallel that you properly balance the flow so that it is equal in each loop. Remember flow will always take the path of least resistance! You can purchase a Quick Setter Flow meter to balance each loop (see below).
  • Page 43: Wiring Option Appendix

    Wiring Option Appendix Wiring – HEATING Hydronic Pump (HY) EcoULTRA is a fully functional hydronic heating controller and has the capacity to control a single zone pump as well as calculate the optimal operating temperature via a built-in reset controller. This is done via the S1 and S2 connection with the supplied outdoor temperature sensor.
  • Page 44: Wiring - Heating Fan Coils (Fc)

    Wiring – HEATING Fan Coils (FC) The Fan coils are equipped with their own thermostat mounted on the unit as well as an internal 3-way valve, and pump output activation switch. The setting of the fan coil should be set to HEATING. When a heating call is generated by the units, the fan coil will open the internal 3-way valve and close its pump output switch.
  • Page 45: Wiring - Heating Air Handler (Ah)

    Wiring – HEATING Air Handler (AH) The Arctic Air Handler will optimize the air flow over its oversized heat exchanger when a heating call occurs from an external room thermostat. When a “W “ heating heat call is received the control board on the LV-Z will activate an external zone pump causing hot water to flow through the heat exchanger and the fan to turn on to its optimal fan speed.
  • Page 46: Wiring - Cooling Fan Coil (Fc)

    Wiring – COOLING Fan Coil (FC)* The fan coils are equipped with their own thermostat mounted on the unit as well as an internal 3-way valve, and pump output activation switch. The setting of the fan coil should be set to Cooling. When a cooling call is received by the units, the fan coil will open the internal 3-way valve and close its dry contact switch (remote on).

  • Page 48: Wiring - Cooling & Heating Air Handler (Ah)

    Wiring – COOLING & HEATING Air Handler (AH)* The Fan coils are equipped with a relay that is activate in heating call. When an external room thermostat calls for heating it will activate a “W” heating call. This in turn will signal the fan coil to optimize its speed for heating.
  • Page 49: Modifying A Standard Tank To A Buffer Tank

    *Note In multi-mode such as hot water “and” cooling shown in the layout, the heat pump will always take the hot water mode as priority. As most system designs will use the internal hot water heat exchanger in the EcoULTRA tank, it will require that the hot water tank is first satisfied before activating a cooling call.
