Hydro Unit Control
8) Hot water cylinder thermostat control
Hot water can be supplied using an existing hot-water cylinder with a thermostat.
8-1) Installing the hot-water cylinder thermostat
• Optional board : TCB-PCM03E optional PC board is required. Connect its connection cable to CN210 port on the
PC board of the hydro unit.
• Wiring with the main unit : After detaching the front panel, install TCB-PCM03E optional PC board in the hydro unit.
Hot-water cylinder heating thermostat : Connect this thermostat between (1) and (2) on TCB-PCM03E.
• Place to install the thermostat (hot-water cylinder) : At a height of 30 to 50 cm from the base.
• Hot-water heater : A hot-water heater is required. (Without a hot-water heater, the hydro unit will not work.)
8-2) Setting the hot-water cylinder thermostat
Setting of DPSW on the hydro unit : DP_SW02_3 = “ON” (Default “OFF”)
8-3) Hot-water thermostat operation (hot-water supply operation only)
If hot water is used when the hot-water thermostat is at the assigned temperature (the circuit between (1) and (2) is
open), the hot-water heat pump starts with the hot-water thermostat closed.
After 30 minutes, the hot-water cylinder heater turns on, but the hot-water heat pump continues running until the hot-
water cylinder thermostat becomes open.
It should be noted, however, that the hot-water heat pump might stop if the water input temperature becomes high.
8-4) Hot-water thermostat operation (hot-water heating operation)
If hot water is used when the hot-water thermostat is at the assigned temperature (the circuit between (1) and (2) is
open), the hot-water heat pump starts with the hot-water thermostat closed.
In 30 minutes, the hot-water heat pump stops. After that, only the hot-water cylinder heater is used to raise water
temperature.
The heat pump switches to heating operation. Unless the hot-water cylinder thermostat temperature rises, the hot-
water heat pump will never take over.
8-5) Hot-water thermostat operation (hot-water cooling operation)
For automatic switching to hot-water supply plus cooling operation, FC-0F is required.
If hot water is used when the hot-water thermostat is at the assigned temperature (the circuit between (1) and (2) is
open), the hot-water heat pump starts with the hot-water thermostat closed.
In 30 minutes, the hot-water heat pump stops. After that, only the hot-water cylinder heater is used to raise water
temperature.
The heat pump switches to cooling operation. Unless the hot-water cylinder thermostat temperature rises, the hot-
water heat pump will never take over.
