Table 1.8. Connection terminals for digital inputs that control service production.
Heat pump start-up control (EVU signal)
Enables / disables energy production with both the compressor and the auxiliary equipment. In any event, circulator pumps, valves
and other components can be activated to consume energy from the storage systems.
Remote WINTER / SUMMER program selection
Used for remote selection of the heat pump operation program.
DHW production
Enables / disables the DHW production function. If the function is enabled, DHW production is governed by the DHW configuration
in the heat pump controller.
Pool production
Activates / deactivates pool production demand. If the signal is requested, pool production is governed by the pool configuration in
the heat pump controller.
5.13. Inside environment control
The heating and cooling functions can be controlled by digital signals from relay thermostats, by interior terminals with thT bus
communication, by a combination of both or not using any interior control terminal.
Relay thermostats
Each outlet unit, from DG1 to SG4, has two 24Vac or 24Vdc digital signals to activate heating or cooling requests from the interior
thermostats or other external control devices.
Table 1.9. Connection terminals for digital inputs that control outlet units DG1 - SG4.
A single thermostat or several thermostats connected in parallel can be used for each outlet unit, as shown below.
