I have a Garrison RCT 100 with a wireless remote control. I have programmed my timer and the programs work correctly. I want to have the ability to override these programs at times, so I go to program (learn) the remote as per instructions. I hold the right arrow button down at the same time as the On/Off button on the command centre at the same time depressing the channel on (1) button on the remote control. It doesn't seem to work. The command centre immediately goes into the Program mode and cycles through the programs until I stop pressing the right arrow. Can anybody help. TY
