Toronto councillors vow to end police paid-duty requirements

Many say a system requiring hiring of high-priced off-duty police to direct traffic and the like needs to end.

Light fixture with one wire? Help!!

So I've wired a decent amount of switches and fixtures but I'm no expert...so I'm replacing a fixture in a house built in 1987. It has two switches, one being a dimmer, and the fixture. When I took it down it has a group of white wires capped, two whites with a black capped, and both the neutral and hot from the old fixture were tied to the black (hot) from the box. Does this make sense? Do I wire the replacement fixture the same way??? So only one black wire was tied to the fixture Thanks...

Strange heating piping.

I have this job, the heating water is piped from another building and loops through this building. A separate pump pulls the water off this loop and sends it through the building. Return comes back to the loop. Only thing is the Supply and Return take off are only six inches from each other. Upstairs supply pipe splits, and goes to the rear VAV and front VAV. Return only comes from front of building. I looked at the first VAV, supply comes off the front supply pipe. The return goes to a separate return that follows the supply and return going across the ceiling space. In other words there are three pipes??? Ever seen anything like this? BTW they want me to right up a control sequence, including replacing three way valves with two way, with new Frequency drive pumps.

York Residential AC Sizing (Based on SEER Ratings)

Hello,



Is anyone proficient with sizing york residential equipment? They seem to size their evaporator coils to condensing units based on the desired SEER rating/efficiency... For instance, I needed a 2 ton LX condensing unit (14 SEER) but wanted to up it to a 16 SEER rating and was given a 3.5 ton (43k BTU) cased coil. That seemed a bit oversized to me but I was assured by the supplier so I installed it anyways. Now it appears that the system runs very infrequently because it is cooling down the house so fast and I'm concerned that it is not pulling enough humidity out of the air with such a short run time. I also couldnt get my subcool up past 3F, continuing to do so only started to decrease my superheat 8F. I was wondering if the oversized coil had something to do with this? It was a mild day, ambient was only about 65-68F.



So I would also like to ask: Does the system achieve the higher SEER because it runs less? Because I was under the impression that a system achieves greater efficiency if it runs longer, with fewer stops and starts?



Any input would be much appreciated, thx

Need some help to re-enter programming mode for vista-20p

I have vista-20p and 6162rt installed at home without any subscription



Recently I need re-program some sensor, but can't enter program mode any more. I think I have the modified installer code in hand, but when I reboot the panel (unplug the battery and transformer then re-plug the transformer), I pressed * and # and the same time within 50s (panel is in basement, need 10s to come back to main floor). The keypad was light on with a long beep when power is reconnected. When I pressed * and #, there is also a long beep. But the keypad keep showing "Busy - Standby, v10.23 D1". I tried * and # several times within 50s, every time I could get a long beep. After about 1 min, the keypad went back to Ready to arm on screen. I don't if this means the panel was locked by accident to downloader only



Any idea? Thank you

Using irrigation system for garden hose

My house has a 4-zone irrigation system. Three of the zones are sprinklers and the fourth is connected to two hose bibs on opposite ends of the house. I'd like to start using one for watering my garden manually with a hose, but I'm concerned about damaging the system if the pumps on but I'm not continually running the water out of the hose. In other words, if there is nowhere for the water to go when the pump is on (because I am not always spraying water out of the hose), will it damage the system?
