Adjusting the Set Under temperature Thermostat Time of day biasing the thermostat should be mounted so that its flat face is rotated by about 20 toward East from the arrays mounting orientation to help lower the activation criteria during mid mornings after the spa pool temperatures have cooled overnight This rotation also helps to bias the system toward higher temperature in the evenings when the spa pools temperatures are higher Insulation biasing If the thermostat switches on too readily on cool days and or you run your spa at a high preferred temperature then the thermostat should be installed without the silicon insulation Insulation biasing If the thermostat does not switch on readily enough and or you run your spa at a lower temperature then the thermostat should be installed with the silicon insulation Vertex Solar Pool amp Spa Heating System Installation amp User Manual Page 35 Copyright 2015 Optex Solar Pty Ltd All rights strictly reserved 28 Installing the Over Temperature Thermostat 40 C Important If the area of your collector array is oversized for your pool spa and or you have a highly insulated pool spa pool you will require a safety thermostat to prevent the potential overheating of your pool spa The thermostat assembly should always be installed on the DANGER higher temperature OUTLET RETURN SIDE of the collector array General Spa Pool Safety Notice Prolonged bathing in hot wat
