53 Toshiba 8-3. Hydro Unit Control 5) Mixing Valve control (2-temperature heating control) To set different radiator unit supply temperatures or floor heating supply temperatures, the unit performs Mixing Valve control.
54 Toshiba 8-3. Hydro Unit Control 7) Automatic restart control The unit records operation information before a power outage and retrieves the information after the pow er is on again to restart automatically the operation with the inform ation.
55 Toshiba 8-3. Hydro Unit Control 8-2) Piping freeze prevention control 2 TC and TWO activates freeze prevention regardless of a heat pump operation mode. 1) Determination condition: TWO>20°C, 2*T C+TWO<-12°C is continuously detected for 30 seconds or longer.
56 Toshiba 3. Hy dro Unit Control 10) Room temperature thermostat control (Option board TCB-PCM03E is necessary. Connect the connection cable to the water heat exchange board CN211.) When the room thermostat is connected and heating or cooling operates with DP_SW12-4 set to ON, an room thermostat operation is performed.
57 Toshiba 8-4. Outdoor unit control 1) PMV (Pulse motor valve) control Valve opening is controlled using the expansion valve with a pulse motor according to a heat pump operation status. • PMV is controlled between 30 and 500 pulses during an operation.
58 Toshiba 8-4. Outdoor unit control 3) Current r elease control The number of compressor rotation is controlled so that current value of the compressor drive ci rcuit does not exceed the specified value. • The outdoor unit detects the input current.
59 Toshiba 8-4. Outdoor unit control 5) Outdoor fa n control The outdoor side control part controls the number of fan motor rotations by receiving an operation instruction from the indoor side (Hydro unit) control part.
60 Toshiba 8-4. Outdoor unit control 5-2) Hot w ater supply and heating fan control 1) The TE sensor, TO sensor and operation frequency control the outdoor fan.
61 Toshiba 8-4. Outdoor unit control 6) Defrosting control This control defrosts the outdoor heat exchanger. The temperatur e sensor (TE sensor) of the outdoor heat ex changer determines frost formation, and then defrosting is performed in the 4-way valve reverse defrosting method.
62 Toshiba 8-4. Outdoor unit control 7) Winding heating control 1) This control energizes the inactive compressor instead of th e case heater to warm the compressor.
63 Toshiba 8-4. Outdoor unit control 10) High temperature release control 1) To prevent excessive hi pressure rise, operation frequency is controlled by the TL sensor when cooling and by TWO sensor when heating.
