Page 7: Mechanical Installation
The automatic pressure relief valve supplied with the boiler is required to prevent dangerous pressure build-ups in the system in case of system malfunction and may under certain conditions vent hot water. Do not install the system where water could damage rugs, furniture, etc. When piping the relief valve to a drain, check with local authority for recommended method of installation. - Page 8 Electronic Aquastat MAXIMUM WATER TEMPERATURE MINIMUM WATER TEMPERATURE °F Fig. 4 Fig. 5 The outdoor sensor will : Maintain the selected maximum water temperature when the outdoor temperature is at +14° F or colder. b) Automatically and proportionally compensate by varying the water temperature between the maximum and minimum when the outdoor temperature is between +14°F and +50°F.
- Page 9 Set the thermostat above the room temperature. The system should start. Make sure the pump starts running as soon as the system starts. 9.10 Heating stages will be switched ON in sequence at 30 second intervals, confirmed by green lights on the left hand side of the PC board on the TH600 or by red lights on the right hand side on the D22-B.
