Tank Sensor Mode Conguration
Use this mode when the heat pump is controlling itself, with a wired sensor directly installed in the primary storage
tank. In single-pass operation, tank storage temperature will actually be dictated by the heat pump Outlet Tem-
perature Target Tank Temperature and Target Outlet Temperature can be modied independently, to affect on/off
temperatures separately from storage temperatures, if desired.
On the “Congure” Screen
1. Set “Demand Mode” to “Tank”.
2. Set the following parameters as necessary
Tank Mode Demand Sequence
1. When the tank sensor detects a temperature below (Target Tank Temperature - Tank Differential),
demand begins.
2. Heat pump begins heat cycle, modulating its output water temperature to Target Outlet Temperature.
3. When the heat pump detects entering water above (Target Tank Temperature - Tank Differential),
demand ends.

When Tank temp drops to (Target Tank Temp - Tank Differential),
begin heat demand.
Target Tank Temperature 120 140 100-160 Set to desired primary storage tank temperature.
Target Outlet Temperature

120 140 120-160 Target outlet water temperature from the heat pump.

All parameters on the “congure“ screen. Service jumper required.

In Single-Pass applications, Target Outlet Temperature cannot be set lower than Target Tank Temperature. Typically, these will be set to equal values.
2
The e360 requires a 45 degree delta between entering and leaving water temperatures. Do not initiate heat demands above 115 EWT.
External Demand Mode Conguration
Use this mode when the unit is being controlled by an external temperature controller, or by a BMS system.
These systems require tank sensing and control independent of the heat pump; no sensor will be connected to
the heat pump from the tank in these modes. Also refer to Table 10 on page 32.
On the “Congure” screen
1. Set “Demand Mode” to “External”.
2. Set the following parameters as necessary
External Demand Sequence
1. External controller places demand on “Run Enable” contacts OR BMS initiates heat demand.
2. Heat pump begins heat cycle, circulating water through the heat pump
3 When entering water temperature of heat pump is below (Target Outlet Temperature - Inlet Cut out Dif-
ferential), compressor operation begins.
4. When the heat pump detects entering water above (Target Outlet Temperature - Inlet Cut out Differen-
tial), compressor operation ends.
5. Pump will continue to circulate and monitor water temperature until external heat demand is removed.
