Intermatic HB880R – Frequently Asked Questions
1) Will the Intermatic HB880R outdoor timer run LED landscape lights, or does it need an incandescent load?
The HB880R handles incandescent, fluorescent, CFL and LED loads, so low-wattage LED path and facade lighting works on it. That matters because some older mechanical and electronic timers need a minimum resistive load to switch reliably. It runs on 120 VAC, 60 Hz only, so it is for line-voltage devices or the primary side of a low-voltage landscape transformer, not for 12 V lamp circuits directly.
2) Can an Intermatic HB880R plug-in timer stay outside year round, or does it have to be mounted under cover?
It is built for outdoor use in a weatherproof black enclosure, so it can live on an exterior receptacle through the seasons. The body measures 5.375 in high, 5 in wide and 1.875 in deep with a 24 inch cord, so check that a while-in-use outdoor cover has clearance for it, or hang the timer beside the receptacle and let the cord make the connection.
3) What does the astronomical clock on this Intermatic outdoor timer actually do differently from a plain 7-day timer?
An astronomical timer tracks sunrise and sunset through the year and shifts the ON and OFF times with them, so lights come on at dusk in June and in December without anyone touching the unit. A plain 7-day timer fires at a fixed clock time and drifts out of step with the season, which is why property staff end up reprogramming it every few weeks. The HB880R also self-adjusts for daylight saving time, so the two annual trips to reset it go away.
4) How many separate on/off schedules can I program into the Intermatic HB880R?
Fourteen ON/OFF programmable events across a full 7-day cycle. That is enough to give each day of the week its own pair of on and off times, or to double up morning and evening runs on a shorter weekly pattern. Useful for a building where the parking lot lights run one schedule and the weekend pattern differs.
5) Can I run two separate light strings off one HB880R timer?
Yes. The unit carries two grounded receptacles, both switched off the same program, fed by a 24 inch cord. So two fixtures or two strings turn on and off together. If you need two independent schedules you need two timers, since there is one program controlling both outlets.
6) Does the Intermatic HB880R lose its program during a power outage?
No. A AA battery is included and keeps the programming and clock alive while power is out, so the schedule resumes on its own when the circuit comes back. The battery backs up the program, not the outlets, so anything plugged in stays dead until utility power returns.
7) Will this Intermatic timer work for a security lighting application where a vacant unit should look occupied?
It has a random mode, which varies the switching times so the pattern does not read as an obvious timer. Combined with the astronomical sunset trigger it is a common setup for vacant units and seasonal properties. It is a plug-in timer though, so it only controls what you plug into its two outlets, not a hardwired fixture.
8) Can the HB880R control an irrigation valve or a pool pump, or is it lighting only?
Intermatic lists this timer for landscape water control as well as outdoor lighting control, so it is used on irrigation and pool and spa equipment timing in addition to lamps. The limit is the connection: it is a 120 VAC plug-in device with cord-connected receptacles, so the equipment has to be plug-connected and within the timer's electrical rating. Hardwired pumps need a hardwired timer instead.
9) What model number do I order to standardize outdoor timers across my properties?
Order Intermatic HB880R. That is the single model for this 7-day outdoor astronomical plug-in timer, in black, so repeat orders across a portfolio all match and the maintenance crew learns one programming interface.
