CHW cooling coil Error

Hello!

I'm trying to setup an AirLoopHVAC according to figure image description

Heating coil is connected to Boiler loop, and Cooling coil (CHW) is connected to Chiller loop. The air loop has setpoint manager single loop with referenced thermal zone for control. Zone is to be kept at 25ºC maximum, for occupied periods.

When running sim on OS, I keep getting the same warning:

Warning * SizeWaterCoil: Coil="CHWCLGCOIL", Cooling Coil has leaving air temperature > entering water temperature. * ~~~ * Tair,out = 12.800 * ~~~ * Twater,in = 82.000 * ~~~ * ....coil leaving air temperature will be reset to: * ~~~ * Tair,out = 82.500*"

The schedule for cooling coil loop (chiller loop) is defined with water leaving chiller at 7ºC, so i find this a bit surreal. I've checked the coils connection nodes and they are differently numbered so a think this is not the problem.

Why do I keep getting the error/warnig above?

Thankyou
