Specifications

Air Systems
• Day (normal), night (economy) and unoccupied (stand by).
• Lockout code on screen gives direct diagnostics.
• ON/OFF or programmable from dip switch setting.
• Day or night programmable state avoids wide internal
temperature variation.
• 3 preset and 3 programmable proles.
• Temperature override.
• Select the control sensor you want to use (integrated in
the thermostat, return air in duct or room sensor).
• Turbo, normal or economy logic from dip switch
setting.
• From –3°C to +3°C sensor offset.
• Average temperature with room or duct sensors.

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 maximizing the efciency.
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. Last 10 lockouts stored in a non-volatile memory.
• 4 heating stages on hot water heating.
• BMS connection (N2 Open protocol).
The Yktool is the perfect tool to use on a regular basis for comissioning and service on site. For comissioning, it will
override the thermostat and start the cooling or heating stages. Being a plug and play device, you will have direct
acess to all sensors and status of each components and accessories installed (lockout & incidents, temperatures,
defrost test...).
