The Range Powermax 155 is a thermal store gas-electric boiler system used to heat water. This design combines both a hot water cylinder and a standard boiler unit together in a single appliance. Users can set specific times for the unit to turn on and off throughout the day, or use the preset times already programmed into the system. The boiler unit needs to be lit before the system is functional, so this system is not recommended for use by children.
Press the "Set" button to begin setting the programmer clock. Use the "Plus" and "Minus" buttons to select the correct day of the week. Press the "Enter" button to confirm the day setting.
Use the "+" and "-" buttons to select the correct time of day. Make sure to also select either "AM" or "PM" time. Press and hold either the "+" and "-" keys to advance time very quickly.
Press the "Enter" button to confirm the time, then press the "Set" button to exit out of the "Clock" menu.
Press the "Set" button twice to select the "Prog" function.
Use the "+" and "-" buttons to select a day of the week to edit, then press the "Enter" button. The display will show "1 On" and then the time for that day's first run time.
Use the "+" and "-" buttons to set a new time for the unit to first come on. Press "Enter" to confirm, then use the "+" and "-" buttons to set a time for the "1 Off" setting. Press "Enter" to confirm the off setting, then continue in this manner to set the on and off times for the second and third on/off settings for that day.
Switch the "On/Off" lever to the "|" or "Hot Water Cont" position to turn on the boiler. The burner will light up and a green light will glow when the burner is functional.
Press the "Advance" button to skip the current on or off setting and advance to the next one. Press the "Advance" button again to cancel the advance command and revert back to the previous on or off setting.
Press the "HW Programme Select" button to cycle through the different program settings offered. Press the "CH Programme Select" button to cycle through the central heating settings available.
