Led Diagnostic Code
The YKlon is a controller regulating all components and accessories. It will pro actively
manage cool and heat stages to maintain a stable room temperature.
Additionally, the benets are:
• Redundancy on cool and heat stages (if one step is locked out, the PCB
starts another one automatically).
• Random start between units to minimise electrical tariff.
• All stages will start in sequence to reduce peak inrush.
• Reduces nuisance calls by using 3 times “you are out” on all safeties
before a hard lockout occurs.
• Automatic restart after power failure.
• Compressors run time priority.
• Alarm output relay and led diagnostic code.
• No parameters to check before starting.
• Lockout and incident level of protection.
• Use a standard 2-stage thermostat but get 98% of YKlon features.
• Last 10 lockouts stored in a non-volatile memory.
• 4 heating stages on hot water heating.
Features and benets YKtool
• Cooling and defrost test.
• Reverse cycle, gas, hot water and electrical heating test.
• Give access to input and output of the YKlon.
• Give access to accessories status and read the probe values.

Thermostats with integrated sensors
The YKPhone485 is a complete communication pack that YORK can offer in order to
provide a local network between units. Without any specic communication protocol
knowledge, you can download the software and have a direct access to the units,
change thermostat parameters, reset lockout, etc…. For more detail, see the following
pages or contact you local agency.
