YORK YMPA0100 AMICHI - BACnet / Modbus

[Timothy]

Hi,

Recently installed a York YMPA0100 AMICHI unit for brine purposes only...
Is there a cheap/easy solutions for using a plain switch to use two setpoints?
During the day we need two different setpoints (-10°C and 0°C).
The operators simply want to use a toggle switch to change the setpoint...


Could this be done without a BacNet / Modbus unit?
I'm not familiar with this kind of protocols...



Thanks in advance,
Have a great weekend!

Hi
Put 2 thermostats with 2 set point
Then put one key 1-0-2
Thermostat 1 comes to 1
Thermostat 2 comes to 2
