This regulation is associated with both the heating and the cooling mode. To prevent errors in the readings of theambient probe, the PERIODIC VENTILATION function was provided, activated both in cool and in heat.Evolution of temperatureONFanOFFHeat mode operationONFanOFFCool mode operation88

AccessoriesThermostatic regulation of the cross valveIn this case, the management of the fans differs depending on operation in heating or cooling, as explained below:- Cooling: Thermostatic regulation opens / closes the valve according to demand, while the fan is always active, even when thethermostatic regulation has reached the temperature(min, med, or max position ) or starts and stops according to demand (autoposition) and periodic ventilation.- Heating: The thermostatic regulation opens/closes the valve while the fan is controlling the HOT START and PERIODIC VENTILATIONfunctions with the corresponding delay times.Evolution of temperatureONValveOFFHeat mode OperationONFanOFFONValveOFFCool mode OperationFan ONcontinuoOFFFanautoONOFFHeating/ cooling with thermostatic regulation in the cross valveThe management of the cross valve carries out an ON / OFF control with indicator of valve closure on reaching the set point, depending on thehysteresis cycles of the heating / cooling diagrams. The valves to be used are of the normally closed type, with electrothermic actuators withopening/closing times of approximately three minutes.The fan is controlled by timer as explained in the paragraph VENTILATION CONTROL, to constantly capture the ambient temperature.Position of the water probeWaterTemp.Water probe position89

To fit the diagrams to the wall model, the variationvalues must be substituted in the following manner:- Cooling mode: the values +1, +2, +3 change to +0.6, +1.2, +1.8- Heating mode: the values -1, -2, -3 change to -0.6, -1.2, -1.8Fan SpeedFan Speedset pointEnviroment Temp.Cool ModeHeat Modeset pointEnviroment Temp.Note: The set point stated on the axis of abscissas of the diagrams refers to the value programmed in the potentiometer by the user.90

AccessoriesPeriodic ventilationIn the case in which the control is imbedded in the machine, when the fan is turned off due to having reaching thermostatic regulation, ON /OFF cycles of the fan shall be carried out, to allow the air probe to capture the actual ambient temperature. Said function is activated both inthe heating and cooling mode.HOT START functionThis consists of the pre-heating of the battery prior to starting the fan. This function is only active in heating mode and can be done in twoways:- Ventilation time delay: for controls with thermostatic regulation in the cross valve there is a fixed delay timing of 180 seconds betweenthe activation of the heat regulator and the activation of the ventilation, to allow the valve to open completely. After 180 seconds the fanwill start up when the water probe reaches a temperature greater than or equal to 39.5ºC. This function does not exist in the controlswith thermostatic regulation in the fan.- Ventilation start-up: The fan starts up when the water temperature is greater than 39.5ºC; this function exists in both the controls asthermostatic regulation in the valve and in the fan.Valve / Fan ON38.5°C39°C39.5°CWater temperature ºCHysteresis diagram of the thermostatic regulation (valve or fan, depending on the type of controller).Post-ventilationAfter disconnection by thermostat of the electric elements, ventilation continues in operation for 90 seconds, in order to cool the elements.91
